USER NOTES

Chapter 2. Applications and Ordering Information

2.1 Protective Relay Applications Using Frequency Shift Carriers

The TCF–10B carrier set is particularly suitable for the following types of protective relay systems:

• Directional Comparison Unblocking

• Permissive Overreaching Transfer Trip (POTT)

• Permissive Underreaching Transfer Trip (PUTT)

• Dual Phase Comparison Unblocking

• Segregated Phase Comparison Unblocking

• Direct Transfer Trip

2.1.1 Directional Comparison Unblocking

The Directional Comparison Unblocking systems transmit a continuous blocking signal, except during internal faults. The channel is generally a frequency-shift keyed (FSK) power line carrier. For an internal fault, the FSK transmitter is shifted to the “unblock” frequency. The transmitted power in many applications is normally 1 W, boosted to 10 W during unblock operation.

The frequency-shift channel is monitored continuously to prevent tripping when a loss of channel occurs. The carrier receiver logic is shown in

Figure 2-1. Under normal conditions, a block frequency is transmitted and OR-1 has no input. Because AND-1 and AND-2 are not satisfied, OR2 is not energized. For an internal fault, the block frequency is removed. Assuming that the unblock signal is shorted out by the fault, OR-1 provides a direct input to AND-2 to satisfy its input requirements for 150 ms. AND-2 inputs to OR-2 to operate the RR or to provide input to the AND shown in Figure 2-3. Without an unblock signal, 150 ms is allowed for tripping. After this period, lock out is initiated as one of the inputs to AND-2 is removed. This resets the RR or removes the input to AND. If the unblock signal is received, it inputs directly to OR-2 to energize the RR or to provide input to AND. The unblock signal also removes an input to AND-1 to stop the timer. A channel failure (no block or unblock signal) provides input to AND-1 and, after 150ms, locks out the relaying and triggers an alarm. The operation of the scheme shown in Figure 2-3 is given in Table 2-1 for external and internal faults. The phase and ground trip fault detectors at both stations must operate for all internal faults; that is, they must overreach the remote bus.

The dependability and security of Directional Comparison Unblocking systems make them the most attractive of the protective schemes for transmission lines using power line carrier channels. Over-tripping is avoided by continuous blocking and continuous channel monitoring.

Only an external fault within 150 ms after channel failure can result in over-tripping.

and the remote terminal(s). A sample schematic is shown in Figure 2-2.

You may conserve frequency spectrum by using a narrow band frequency shift carrier, but at the expense of channel speed (see Chapter 1, Specifications).

Another consideration is an open breaker situation. When the remote breaker is open for an extended period of time, the relay system must be able to trip. The remote relay system sends a trip signal when detecting a remote open breaker. If this remote signal is received for 1,000 ms (1 sec) or longer, the carrier receiver logic interprets this as an open breaker and allows the local end to trip

2.1.2 Permissive Overreaching Transfer Trip Systems

Overreaching transfer trip systems require a channel signal to trip, and are used with a frequency-shift audio tone, modulated on a communication channel (e.g., public or private telephone lines). These systems are generally not used with power line carriers. There are, however, successful applications of power-line carrier on POTT schemes where parallel lines allow for cross-coupling of the carrier signal.

2.1.3 Permissive and Non-Permissive Underreaching Transfer Trip Systems

For overreaching systems, the directional phase and ground trip fault detectors (P) must be set to overlap within the transmission line and not overreach any terminals (see Figure 2-4).

That is, at least one trip fault detector (P) must operate for all internal faults, and none should operate for any external fault. In practice, distance relays are normally required for both ground faults and phase faults, although directional instantaneous groundovercurrent relays might meet these requirements in some cases.

Though it is the least complex, the non-permissive system is rarely used because of the high potential for false outputs from the channel,

which would cause incorrect tripping. If a non-permissive system is used, the channel considerations should be as described later for direct trip systems. The system is made permissive by the additional set of phase and ground overreaching fault detectors (FD), which must operate for all internal faults (see Figure 2-4).

Operation of the underreaching transfer trip scheme shown in Figure 2-4 is described in Table 2-2 for external and internal faults.

Because the trip fault detectors (P) do not operate for external faults, underreaching transfer trip systems do not require external

fault-clearing coordination circuits (transient blocking) and are, therefore, inherently simpler than any of the other schemes. You obtain maximum security if you use additional permissive fault detectors. These schemes also provide minimum operating times for many faults that are tripped directly, without using the channel.

Phase Comparison Pilot Relaying System.

2.1.4 Dual Phase Comparison Unblocking Systems

Dual comparison systems require a duplex channel: one frequency for each line terminal. The TCF–10B frequency-shift channel equipment is available for this purpose; normally used in an unblocking system. Continuous channel monitoring is also provided, because either a trip positive or trip negative carrier signal is always transmitted.

The transmitter is keyed to its trip positive frequency when the square wave from the filter goes positive, and is keyed to its trip negative frequency when the square wave is at zero. There are two outputs at the receiver: the trip positive output is a square wave that goes positive when a trip positive frequency is received; the trip negative output goes positive when a trip negative frequency is received.

The basic operation of the Dual Phase Comparison system is shown in Figure 2-5. For internal faults, the single phase outputs of the sequence current networks are essentially in phase, although such output represents currents 180° apart in the power system. The network output goes through a squaring amplifier that keys the frequency shift transmitter. An adjustable delay circuit delays the local square wave by a time equal to the channel delay time.

The network output is then used to develop two complementary square waves. One wave, which has a positive state during the positive half-cycle of the sequence

current network, is compared with the receiver’s trip positive output. The other wave, which has positive output during the negative half-cycle of the sequence current network, is compared to the receiver’s trip neg. output in a second comparison circuit.

On internal faults, the positive half-cycle of the local square wave lines up with the received trip positive output to provide an AND-1 output (see Figure 2-5). On the negative half-cycle, this local square wave lines up with the received trip negative output to provide an AND-2 output. If an arming signal is received (FD

and/or 21P) and either AND-1 or AND-2 output exists for 4ms, an input to the trip flip flop initiates breaker tripping. The same operation occurs at both terminals, tripping breakers 1 and 2 simultaneously on either half-cycle of fault current.

For tripping, both the trip positive and trip negative frequencies must be transmitted through the internal fault via power line carrier channels. If these frequencies are not received, the receiver detects a loss of channel and clamps both outputs to a continuous positive state. This loss of channel clamp enables both comparison circuits, allowing the system to trip on the local square wave input only. After 150ms, the system output clamps these to the zero state. At this point, the system cannot trip and is locked out. An alarm indicates loss of channel.

For external faults, the reversal of current at one end shifts the square waves essentially 180°. As a result, neither AND-1 nor AND-2 has the sustained output required to operate the 4ms timer (see Figure 2-5). No trip occurs at either line terminal.

2.1.5 Segregated Phase Comparison

System

The Segregated Phase Comparison system has been developed to improve pilot relay protection, particularly for the long EHV series capacitorcompensated transmission lines. Long EHV series capacitor-compensated lines are a source of significant transients during the fault period. Under these circumstances, sequence current networks designed to operate at normal system

frequency may present a problem. The experience with these Phase Comparison systems has, however, been remarkably good. Directional Comparison systems, on the other hand, are subject to mis-operation on series capacitorcompensated lines, particularly if the capacitor gaps do not short the capacitors on faults. Segregated phase comparison systems, which are current-only, are independent of the following phenomena:

• Power system frequency and wave form

•Effects of impedance unbalance between the power system phase circuits.

• Maximum load/minimum fault current margin.

The segregated phase comparison system can be divided into two types: a two-subsystem scheme and a three-subsystem scheme. In the twosubsystem scheme, one subsystem operates from delta current (I

a-Ib

) for all multi-phase faults, and

a ground (3I

) current subsystem operates for all ground faults. The three-subsystem scheme has a subsystem for each phase (I

, Ib, and Ic). Each subsystem consists of one channel (TCF–10B) and one Phase Comparison relay.

Both segregated Phase Comparison systems incorporate “offset keying,” enabling them to trip for internal high-resistance ground faults and internal faults with outfeed at one terminal. No other system can clear these types of faults without extra logic or channels. On a 500 kV line with a 2,000:5 current transformer ratio, for example, the three-subsystem scheme will operate for ground-fault resistances up to about 100 Ω primary impedance. Under the same conditions, the two-subsystem scheme will operate up to about 200 Ω primary fault resistance.

The two-subsystem package is suitable for all applications except single-pole tripping, where the three-subsystem package must be applied. The basic operation of the scheme is illustrated in Figure 2-6. Each current is fed through a noninductive resistor, supplying a voltage output to the squaring amplifier (SA) that is exactly proportional to the primary currents. The output of these amplifiers is used to key the individual channels and, through the local delay timers (LDT), to

provide the local square waves for comparison. The timers are adjustable between 2 and 20ms to compensate for the delay time of the channel. This digital delay circuit translates the pulse train independently of the pulse width ratio, in contrast to the ac phase angle shift used in the other systems. The ac phase shift delay uses frequencydependent components, which are accurate only at system frequency and can “ring” during transient conditions.

The square wave comparison is made independently for each current in the separate subsystems. Separate channels are required for each of the subsystems. One of the comparison circuits is shown in simplified form in Figure 2-7. In this dual comparison circuit, AND-P is used for the positive half-cycles and AND-N for the negative half-cycles. As shown in Figure 2-7, the received positive square wave corresponds to a “1” input to AND-P, and the received negative square wave to a “0” input, negated to “1”, into AND-N. Except for this variation, operation is as shown by the square wave blocks in the lower half of Figure 2-5.

To generate the local and keying square waves, conventional phase comparison systems use thresholds equivalent to (or very near) the zero axis. As a result, an internal fault with outfeed looks like an external fault to those systems (see Figure 2-8). The offset keying technique permits the relay system to trip for internal faults with outfeed current out at one terminal. While the outfeed condition is very unusual, it presents difficult problems to the great majority of pilot relaying systems when it does occur. Outfeed can occur in any of the following cases:

• Series-capacitor-compensated parallel lines.

•Weak-feed or zero-feed applications, particularly with heavy through load.

• Some multi-terminal applications.

• Series-compensated (line-end compensation) line with a source inductive reactance smaller than series capacitor reactance.

• Some single-line-to-ground faults, occurring simultaneously with an open conductor, where the fault is on one side of the open conductor.

• Some single-line-to-ground faults with high fault resistance and heavy through load (such conditions can cause outfeed only in the faulted phase current, not in the ground subsystem).

The offset keying technique allows the relay system to work like a true current differential scheme. The scheme takes advantage of the fact that, for the outfeed condition, the current into the line is greater in magnitude than the current out of the line for the internal fault.

This relationship is illustrated in Figure 2-8, where I

equals IFplus IH. While the two terminal currents may have any angular relationship with one another, most outfeed conditions display a nearly out-of-phase relationship. The out-of-phase condition illustrated is the most difficult case for phase comparison, as well as the most common outfeed condition.

In the offset keying technique, the keying threshold is displaced in the positive direction, away from the zero axis. The local square wave thresholds are displaced negatively. To maintain security, the local thresholds are separated from each other, providing “nesting” during external faults. Typical settings are shown in Figure 2-9.

Figure 2-10 illustrates the square wave characteristics of offset keying for normal internal faults, external faults, and internal faults with outfeed.

The segregated Phase Comparison scheme incorporates a high degree of security. Its design is based on extensive field experience and the model line tests for the very long, series capacitorcompensated EHV lines.

Output trip signals are supervised by an arming input and a number of security checks (see Figure 2-8). Phase arming is performed by a current rate-of-change detector that responds to sudden increases, decreases, or angular shifts in current. It operates on current changes of 0.5 A or more, with an operating time of 2 ms. Ground

Security checks to comparison AND (see Figure 2-8) include (1) low channel signal blocking, (2) lockout for sustained low channel signal, (3) channel noise clamp, and (4) receive guard block. For the phase subsystems, a trip signal occurs if comparison AND has an output for more than 3ms (4ms for the ground subsystem).

2.2 Direct TransferTrip Systems

Direct transfer-trip systems provide circuit-breaker tripping at remote or receiver terminals, without any supervision by fault detectors. The most important consideration in a direct transfertrip system is the type of channel applied. The communications equipment must carry the total burden of system security and dependability.

Direct transfer-trip systems are applied for:

• Line protection with nonpermissive under reaching transfer-trip systems.

•Transformer protection where there is no circuit breaker between the transformer and transmission line.

• Shunt reactor protection.

• Remote breaker failure protection.

A sample schematic is shown in figure 2-11.

2.2.1 Transformer Protection

A typical transformer protection scheme is illustrated in Figure 2-12. A direct trip channel is keyed to the trip state when the transformer protective relays operate. The received trip signal will then trip the remote end breaker and lock out reclosing.

Although it is no longer widely used, you may use a ground switch operated by the transformer protective relays for transformer protection. In this technique, a ground fault is initiated on the transmission line at G, providing adequate fault current for the ground relays at H to trip the breaker at H. This system is slower but is widely used on lower voltage systems and is fairly simple and straightforward. It does not require any secure communication medium between G and H. For this type of application, the ground relays at H can be set to operate for 100 percent of the line and not overreach to bus G.

While a single switch on one phase is normally applied, you may use a double switch on two phases to initiate a double-phase-to-ground fault. In the latter case, both phase and ground relays can operate to ensure redundancy. Fault grounding is not applicable to all systems because of high short-circuit capacity.

2.2.2 Shunt Reactor Protection

Shunt reactors are frequently used on HV and EHV lines. These line reactors are connected on the line side of the circuit breakers (see

Figure 2-11). A remote trip channel is thus required for a fault in the shunt reactor.

2.2.3 Remote Breaker-Failure Protection

A remote breaker-failure system is necessary where a multi-breaker bus, such as a breaker-anda-half or ring bus scheme, is applied at a transmission line terminal. A direct transfer-trip system will be a part of the remote breaker-failure protection.

2.2.4 Direct Trip Channel Considerations

The channel and its terminal equipment are major factors in the proper operation of the direct transfer-trip system. The channel must neither fail to provide a correct trip signal nor provide a false signal.

While other types of modulation are possible, frequency-shift keyed (FSK) equipment offers the best compromise between noise rejection capability and equipment complexity. Two frequencies are usually transmitted in an FSK system: the “guard” frequency is transmitted during non-trip conditions and the “trip” frequency is transmitted when a breaker trip is required. Because a signal is always present, the FSK system will allow the channel to be continuously monitored. Continuous channel monitoring is necessary in a direct trip

system, because breaker tripping is not supervised by any local relays.

As noise in the channel increases, a point is reached where there is a high probability of false tripping. The level of noise at which the channel becomes unreliable must be determined by tests. Signal-to-noise ratio monitors must then be included with any direct trip channel, to block possible false tripping. It is important, however, not to get the noise monitors any more sensitive than required, since their operation will prevent tripping.

There are three important aspects to the application of FSK channels to direct trip systems: channel bandwidth, dual channel systems, and channel protection.

Although faults should be cleared in the shortest possible time, speed is not the only criterion for selecting equipment. It is important to use the narrowest bandwidth equipment possible. A wide bandwidth channel may give the desired speed, but more noise enters the system. Thus, the channel will block tripping sooner than a narrower bandwidth channel with the same received signal level. A wideband channel will consequently not

be as dependable as a narrower channel under equal receive-level conditions.

A dual channel system is recommended for direct trip applications. Two FSK channels should be used in series, so that both must trip before the breaker is tripped. Many tests have indicated that dual channels improve the security of the direct trip system by several orders of magnitude. Use of a dual channel system has very little effect on dependability, even if both channels are on the same transmission medium.

If you want to increase the dependability, you can modify the dual channel transfer trip scheme to allow a single channel trip when there is failure of the other channel. A typical Dual Channel Throwover to Single Channel Scheme is illustrated in Figures 2-14 & 2-15.

2.3 Special Considerations

The TCF–10B frequency-shift equipment can operate in either the two- or three-frequency mode, but ordinarily operates as a two-frequency system. The three basic frequencies are as follows (see Figure 2-16):

fHHigh-frequency, is a frequency shift (∆f)

fLLow-frequency, is a frequency shift (∆f)

The value of ∆f depends on the bandwidth of the TCF–10B set. For a bandwidth of 1600 Hz, ∆f is 500 Hz. A bandwidth of 380 Hz yields a ∆f of 100 Hz, while the 800 Hz bandwidth ∆f can be

either 250 or 100 Hz, depending on the setting of S5 on the Transmitter Board. The center channel frequency (f

) can vary from 30 to 535 kHz (in

0.5 kHz steps).

In the two-frequency systems, only f

and fLare used. The two frequencies function differently and take on different labels when operating with the different types of protective relay systems.

2.3.1 Directional Comparison

Unblocking (Two-Frequency)

The higher frequency (fH), or “Guard” frequency, is transmitted continually as a blocking-type signal during normal conditions, to indicate that the channel is operative and to prevent remote relay tripping when external faults occur.

For a fault sensed by the local overreaching pilot relay, the transmitter is frequency-shifted to a low frequency (f

), called “Unblock” frequency. The transmitted power is normally 1 W, boosted to 10 W for the “Unblock” operation.

The Directional Comparison Unblocking system will generally use the wide band, wide shift (800 Hz BW, ±250 Hz Shift) TCF–10B carrier set. Also, the most common power output level used will be the 1 watt block and 10 watt trip. The type of carrier applied with this scheme may be varied from the normal for special circumstances, e.g., when matching the new TCF–10B equipment at one end of the line with the older TCF, TCF-10, or TCF-10A equipment at the other end. In this case, you must apply the wide band, narrow shift carrier (800 Hz BW, ±100 Hz Shift) to match the older carrier characteristics.

2.3.2 Transfer Trip: Overreaching, Underreaching or Direct (TwoFrequency)

The higher frequency (fH), or “Guard” frequency, is transmitted continually during normal conditions. For a fault sensed by the overreaching (or underreaching) pilot relay, the transmitter is shifted to the low frequency (f

), called “Trip”

frequency.

When using the TCF–10B for any permissive overreaching or underreaching line relay system, you can apply any bandwidth set. However, the best all around set to use will be the wide band, wide shift (800 Hz BW, ±250 Hz Shift) equipment. If signal-to-noise ratio is of concern, however, you may use the narrow band set; on the other hand, if relay speed is critical, you may apply the extra wide band (1600 Hz, ±500 Hz Shift) equipment. If, in direct transfer trip systems, security due to S/N is of concern, we strongly recommend that you apply only narrow band equipment. In any of these systems, the usual power level combination will be 1 watt for guard and 10 watts for the trip signal.

2.3.3 Phase Comparison Unblocking: Dual or Segregated (Two-Frequency)

Phase Comparison relays use square wave signals for operation. The transmitter is keyed to a “Trip Positive” frequency when the relay square wave goes positive, and is keyed to a “Trip-Negative” frequency when the relay square wave is at zero. The Trip Positive frequency is frequency-shifted below f

; the “Trip Negative” frequency is

frequency-shifted above f

. Either frequency can function as a trip or block, depending on the local square wave.

For Phase Comparison systems, you can use only the wide band with wide shift or extra wide band TCF–10B. In the interest of conserving spectrum, the wide band, wide shift channel is most common. However, if speed is important, you may apply the extra wide band set. The most often applied power level will be 10 watts for both “Trip-Positive” and “Trip-Negative”.

Chapter 2. Applications and Ordering Information

2.3.3.1 Phase Comparison Relaying and

20V Auxiliary Power Supply

When ordering a TCF-10B for use with phase comparison relaying, a 20V auxiliary power supply is provided.

The majority of interfaces between the relay and the communications equipment are done at the station battery. If the control battery is 125 Vdc, then the carrier output will be powered up with 125 Vdc to provide station battery voltage to the relay. However, in phase comparison relay systems, the ratio, of the on and off state, of the carrier circuit ouptut and the on and off state of the relay’s keying circuit is critical to provide a square wave that closely represents the power system ac wave. Therefore, based on the type of inputs used on the relay system at the point it interfaces with the carrier system, this will determine what voltage level is acceptable. This criticality is on the order of 500 or less microseconds.

Due to the capacitors typically applied to output circuits to dampen surges, the higher the voltage applied, the longer it will take to dissipate the energy. Therefore, to dissipate this energy quickly, to adhere to the timing requirements for a secure phase comparison relay system, the use of the auxiliary 20V power supply is necessary. Different relay manufacturers’ input circuits may vary and can conceivably decay fast enough not to hinder the security of the relay system operation. However, the energy dissipated will also generate a significant amount of heat. By utilizing the auxiliary supply, mounted on the rear of the

carrier unit, it will allow that heat to be outside of either unit.

Pulsar strongly recommends the application of the auxiliary power supply for two reasons; decay time of the energy, and the heating caused by the dissipation of energy.

2.3.4 Three-Frequency Systems

The TCF–10B also provides for three-frequency system applications (see Figure 2-16), e.g., Directional Comparison Unblocking with Direct Transfer Trip, or Permissive Overreaching Transfer Trip with Direct Transfer Trip. All three frequencies are closely-controlled discrete frequencies within the equivalent spacing of a single wideband or extra wideband channel. In applying a three-frequency system, the Direct Transfer Trip keying inputs shifts the channel low (i.e., –250 Hz for 800 Hz bandwidth) and the unblock key shifts the channel high (i.e., +250 Hz for 800 Hz bandwidth).

See figure 2-17 for a sample schematic.

2.3.5 Three terminal line applications.

When a three terminal line protection requires power line carrier equipment, each terminal must have one transmitter and 2 receivers, since each terminal must receive a signal from each of the 2 other ends of the line. Fig. 2-18 is a representation of the transmitter/receiver complement required to implement a single function: Hybrids or other isolation devices are required between transmitters and transmitters to receivers. See the following section for details.

2.4 Hybrid Applications

The purpose of the hybrid is to enable the connection of two or more transmitters together on one coaxial cable without causing intermodulation distortion due to the signal from one transmitter affecting the output stages of the other transmitter. Hybrids are also required between transmitters and receivers, depending on the application. The hybrid circuits can, of course, cause large losses in the carrier path and must be used appropriately. High/low-pass and band-pass networks may also be used, in some applications, to isolate carrier

equipment from each other. Several typical applications of hybrids are shown in the following diagrams, Figures 2-19 through 2-23. A summary of some of the more important application rules are given below:

1. All hybrids in a chain should be resistive type hybrids except the last hybrid, that is, the one connected to the line tuner.

2. The last hybrid in the chain should be the reactance type hybrid or a skewed type.

3. When applying transmitters to reactance type hybrids, the frequency spacing between the widest spaced transmitters is about 4% for frequencies below 50 kHz and 6% for frequencies above 50 kHz. If this rule is not followed then the hybrid cannot be adjusted to provide the best possible isolation between all transmitters.

4. When applying transmitters and receivers to a reactance type hybrid the frequency spacing between the transmitter group and receiver group is of no concern; however, all the transmitter frequencies must meet the frequency spacing rule above. This rule is based on receivers with high input impedance.

5. When the last hybrid is a skewed type then the receiver port should be terminated with a 50Ω resistor to obtain proper isolation.

Afew guidelines follow in order of importance:

1. The hybrids should be arranged with the lesser losses in the transmitter path and the greater losses in the receiver path to provide more transmitter signal levels onto the power line.

2. Transmitters that are used with wide bandwidth channels should be arranged with lower losses and those of narrower bandwidths should have the higher losses.

3. Narrow band systems are not as susceptible to noise as wider band systems are, therefore they can tolerate the higher loss.

If possible, transmitters used for common applications should be arranged for equal attenuation. This would apply to systems that use dual channels such as Direct Transfer Trip (DTT) or Segregated Phase Comparison.

Following are the type of hybrids and their associated style numbers.

2.4.1 Examples

Following are several figures that illustrate possible hybrid applications. A short description of each follows.

In these illustrations, Resistive Hybrids are denoted as R hybrids, Reactive hybrids as X hybrids and Skewed hybrids as S hybrids. Fig. 219 illustrates two transmitters being combined onto a single coax cable for connection to a line tuner. This would be a typical application for a dual channel, uni-directional trip system. The receive end of the system would not require a hybrid so that the receivers would be tied together via coax cable before connection into the line tuner.

When only one transmitter and one receiver are required as in a single channel bi-directional transfer trip system or a directional comparison unblocking system Fig. 2-20 can be applied. A skewed hybrid may be used in place of the

reactive hybrid (X hybrid). The skewed hybrid has a designated transmit port and receive port.

When two transmitters and two receivers are being applied to a single coax cable, as in a dual channel bi-directional direct transfer trip system, Fig. 2-21 is appropriate.

Four transmitters used for similar applications can be combined as shown in Fig. 2-22. This would be representative of two dual channel uni-directional

transfer trip systems. This provides equal losses to each transmitter.

When different types of modulation and different bandwidths are utilized, it is better to arrange the transmitters and receivers as shown in Fig. 2-23. This allocates loss based on performance factors of the modulation type and bandwidth.

2.5 Ordering Information

The equipment identification number (catalog number) is located in the center of the TCF–10B front panel. The TCF–10B catalog number comprises nine (9) characters, each in a specific position.

Figure 3–2. Cable Termination Diagram (9651A13).

3.6.2 TCF–10B Equipment Ground

In addition to the TCF–10B chassis ground connection that is made through the cabinet or rack, a ground connection is provided at the Rear Panel Terminal Block (TB7). (See Figure 3-1 and Figure 3-4.) A connection should be made between TB7 Terminal 6 and the ground connection at the TCF–10B cabinet location.

3.6.3 DC Power Supply and Other Connections

Input/Output terminals, on the rear of the TCF–10B chassis, provide the connection points for the power supply (48, 125, and 250 Vdc) and customer interconnections. (See Figure 3-1 and Figure 3-4). The terminal blocks on the rear of the chassis can accept up to a 12 AWG wire with a ring lug type Burndy YAV10C36 or YAV10 or equivalent.

Any lead coming to or from the switchyard should be shielded twisted pair to protect against transients.

3.6.4 Coaxial Cable

A coaxial cable is required for a low-impedance path between the TCF–10B (Transmitter and Receiver modules) and the Line Tuner (in the switchyard). Connection jacks (J1 & J2), on the Rear Panel, provide the point for coaxial cable connection from the TCF–10B to the switchyard.

The type of coaxial cable we recommend is RG213/U (52Ωs, 29.5 pf/foot):

• Single-conductor

• #12 AWG

•7 strand #21 copper

• Polyethylene insulator

• Copper shield

•Vinyl jacket (nominal O.D. 0.405 inch)

If the coaxial cable is to connect to related cabinets enroute to the switchyard, you should connect the RG-58A/U cable ||(and Amphenol #83-58FCP or equiv. male UHF connector)|| from J1 or J2 to the related cabinets, and RG-213/U from the cabinets to the switchyard. Install the

coaxial cable according to the following procedures:

1. Attach both ends of the coaxial cable in accordance with the Cable Termination Diagram (see Figure 3-2, terminal block lugs, as required).

2. In order to hold carrier loss to a minimum, keep the cable the shortest possible length.

The minimum cable bending radius is six times the cable diameter.

3. The copper braid of the cable must be grounded at the end which connects to the TCF–10B.

4. Without grounding the copper braid of the cable, connect the cable to the ground

terminal of the Line Tuner, at either of the following:

• Impedance Matching Transformer

•Wideband Filter

If you are connecting the cable directly to the line tuner, the cable connector can enter the line tuner base either through the side or the bottom of the base.

SH Shift Low Key Output

VVoice-Level Key Output

TX Any Transmitter Key Output

5.2.3 Keying Module Jumpers

Remove the Keying Module from the chassis and set jumpers (JU1 thru JU14) as desired.

JU1 Allows you to select between the

NORM/INVERT positions for Power Off. Select the normal (NORM) position to allow a Keying function in the transmitter when proper voltage level (15V, 48V, 125V, 250V) is applied to the input terminals. Select the invert (INV) position to allow a Keying function in the Transmitter when voltage is not present at the input terminals. Set JU1 to invert (INV).

JU2 Selects between a Directional

Comparison system and Phase Comparison system. Set JU2 to DCR (Directional Comparison).

JU3 This link allows you to select between

a 1W (Guard)/10W (Trip) or 10W (Guard)/10W (Trip) operation by placing the link in the 1/10W or 10/10W position, respectively. Select the 1W/10W position.

JU4 Selecting the 2-frequency (2F)

position will set the Keying Module as a two-frequency system. Selecting the three-frequency (3F) position will set the Keying Module in mode to correctly operate as a three-frequency system. Select the 3F position.

JU6 Placing JU6 to the IN position

activates the shift high contact; the OUT position deactivates the shift high contact.*

JU7 Placing JU7 to the IN position

activates shift low contact; the OUT position deactivates shift low contact.*

JU8 Places shift high contacts in either the

normally open (NO) position or the normally closed (NC) position.

JU9 Places shift low contacts in either the

normally open (NO) position or the normally closed (NC) position.

JU10– JU14 Provides input keying voltage selec-

tions: 15/20V, 48V, 125V, 250V.

After setting the jumpers, insert the Keying Module back into the TCF–10B chassis.

5.3 Select TCF–10B Receiver Logic

Set the Receiver Logic PC Board switches (see Section 15.3) in accordance with the TCF–10B application:

• 2-Frequency, Directional Comparison

• 2-Frequency, Phase Comparison

• 3-Frequency, Directional Comparison

December 2004 Page 5–3

Chapter 5. Installation/Adjustment Procedures

*Place in the “OUT” position when using with the Phase

Comparison relay systems.

5.4 Select TCF–10B Transmitter RF Output Impedance

1. Configure the RF Output Impedance.

Remove the RF Interface Module from the TCF–10B chassis and configure the output impedance by setting jumpers:

• JU4 when set, provides 50Ω

• JU3 when set, provides 75Ω

• JU2 when set, provides 100Ω

2. Select 2- or 4-wire Receiver Input, using

jumpers JU1 and JU5:

• IN position for 2-wire (not normally used for TCF–10B)

• OUT position for 4-wire (both JU1 and JU5 must be OUT)

3. If you are using an external hybrid chain, and the receive signal is not high enough, a higher sensitivity may be desirable. Set jumper JU6 to HIGH, if necessary.

4. Insert the RF Interface Module back into the TCF–10B chassis.

5.5 Check Line Tuning and

Matching Equipment

1. Refer to the appropriate instructions for line tuning equipment.

2. Perform the required adjustments.

5.6 Check TCF–10B Transmitter Power Levels and Frequency

Turn “ON” the power and check the dc voltage outputs from the Power Supply Module. Then, turn “OFF” the power and remove the coaxial cable connection to the Line Tuner and substitute a 50, 75, or non-inductive 100Ω resistor termination (in accordance with the jumper settings in

5.4-1).

5.6.1 Check High-Level Output

1. Connect the Selective Level Meter to the 10W

PA Module control panel, at test jacks:

TJ1 Input - Top Jack

TJ2 Common - Bottom Jack

2. Tune the meter to the Transmitter frequency.

3. Turn power “ON” at the Power Supply

Module.

4. On the Keying Module control panel, press

and hold the top push-button (marked HL) to key the Transmitter at High Level power.

The “HL” and “TX” LEDs should show red.

5. Record the Selective Level Meter reading (at

TJ1, TJ2). The meter should measure .224 Vrms (0 dBm at 50Ω reference) for full High- Level keying (10W power). If you measure 0 dBm, skip ahead to Step 8.

6. If the meter does not measure 0 dBm, turn the

power “OFF” at the Power Supply Module and remove the Transmitter Module from the chassis. Place the extender board into the Transmitter Module position of the chassis. Then plug the Transmitter Module onto the extender board.

CAUTION

DO NOT ALLOW INEXPERIENCED PERSONNEL TO MAKE THESE ADJUSTMENTS. PERSONNEL MUST BE COMPLETELY FAMILIAR WITH THE HAZARDS INVOLVED.

7. Turn the Power Supply “ON”. Turn the 10W Adjust potentiometer R13 on the Transmitter Module until the Selective Level Meter (at the 10W PA TJ1, TJ2) reads .224Vrms (0 dBm at 50Ω reference). Then place the Transmitter Module back in the chassis.

If it is desirable to set full power at less than 10W, turn the 10W adjust potentiometer (R13) accordingly. The level at the RF Interface Module (TJ1, TJ2) is 40 dB higher than at the 10W PA Module (TJ1, TJ2).

For example: If 22 dBm is desired at RF Interface(TJ1, TJ2), set potentiometer R13 so that 10W PA (TJ1, TJ2) reads -18 dBm. (The PA gain is adjustable with R53 on the 10W PA Module.)

8. Monitor the output of the 10W PA Module at the RF Interface Module test jacks TJ1 (Line)/TJ2 (Line Common). On the 10W PA Module, adjust potentiometer R53 INPUT LEVEL SET for 22.4Vrms (10W) output level.

9. On the Keying Module control panel, release the (HL) push-button to reduce the Transmitter power.

The “HL” LED should not be red; but the “TX” LED should remain red.

5.6.2 Check Low-Level Output

1. With the conditions the same as for the HighLevel Output check:

• Selective Level Meter at the 10W PA

Module control panel (TJ1, TJ2)

• Meter tuned to XMTR frequency

• Power “ON”

The “TX” LED should show red.

2. With the Transmitter keyed on LL, record the Selective Level Meter reading (at TJ1, TJ2). The meter should measure .0707Vrms (-10 dBm at 50Ω reference) for Low-Level keying (1W power).

3. If the meter does not measure -10 dBm, turn the power “OFF” at the Power Supply Module

and remove the Transmitter Module from the chassis. Place the extender board into the Transmitter Module position of the chassis. Then plug the Transmitter Module onto the extender board.

4. Turn the 1W Adjust potentiometer (R12) on the Transmitter Module until the Selective Level Meter (at the 10W PA TJ1, TJ2) reads .0707Vrms (-10 dBm at 50Ω reference).

5. Repeat step 5.6.1-8 (above) at 7.07Vrms (1W) output level.

6. Turn “OFF” the power supply.

7. Place the Transmitter Module back in the chassis.

We recommend that you set the low level power 10 dB below full power. You may, however, use any power level between 10W and 50mV.

|| 5.6.3 Adjusting Low-Level Output

for a Level Other Than 1W

Should you wish to adjust the low-level output for a level other than 1W, use R12 on the transmitter card to adjust to the level you desire. The following chart gives you several levels that you may use for reference.

For a 10W low-level output, it is easier to move jumper JU3 on the keying module to the 10/10W

position.

5.6.4 Check Voice-Level Output

Perform this procedure only if you are using the Voice Level Output option.

1. With the conditions the same as for the HighLevel Output check:

• Selective Level Meter at the 10W PA

Module control panel (TJ1, TJ2)

• Meter tuned to XMTR frequency

• Power “ON”

2. Key the carrier set by lifting the handset from its cradle, while muting the microphone, to key the Transmitter at Voice-Level (4.3W power, when the High-Level power is set to 10W).

The “V” and “TX” LEDs should show red.

3. Record the Selective Level Meter reading (at TJ1, TJ2). The meter should measure .148 Vrms (-3.6 dBm at 50Ω reference) for Voice Keying. If you measure -3.6 dBm, skip ahead to Step 6.

4. If the meter does not measure -3.6 dBm, turn the power “OFF” at the Power Supply Module and remove the Transmitter Module from the chassis. Place the extender board into the Transmitter Module position of the chassis. Then plug the Transmitter Module onto the extender board.

5. Turn the Voice Carrier Adjust potentiometer (R14) on the Transmitter Module until the Selective Level Meter (TJ1, TJ2) reads .148 Vrms (-3.6 dBm at 50Ω reference). Then place the Transmitter back in the chassis.

If using a full power level (other than 10W), you should set the VF level accordingly, i.e.,

3.6 dB below the high-level value.

6. Monitor the output of the carrier set with an oscilloscope at the 10W PA Module test jacks:

• TJ1

• TJ2

7. Voice key the Transmitter by lifting the handset from its cradle and by whistling loudly (about 1 kHz) to achieve the following voltages:

•~.62V p-p (overall)

•~.20V p-p (valley)

8. If the voltages above (.62/.20) do not approximate a ratio value of 3, adjust the AM Modulation Adjust potentiometer (R11) on the Transmitter, as follows:

• Clockwise if not enough signal (a value

less than 3).

• Counterclockwise if too much signal (a

value significantly greater than 3).

9. Un-key the Push-to-Talk switch (or handset).

5.6.5 Check Transmitter Frequency

1. At the Keying Module, push the recessed push-button “SH” to shift the frequency higher: (f

= center freq. set on front of

module)

+ 100 Hz Narrow Band or Wide Band,

Narrow Shift

+ 250 Hz Wide Band, Wide Shift

+ 500 Hz Extra Wideband, Wide Shift

If the frequency shift is incorrect on the Transmitter Module, check the position of switch S5 for the correct amount of shift.

2. At the Keying Module, release the “SH” pushbutton and push the “SL” push-button to shift the frequency lower:

– 100 Hz Narrow Band or Wide Band,

Narrow Shift

– 250 Hz Wide Band, Wide Shift

– 500 Hz Extra Wideband, Wide Shift

If the frequency is incorrect on the Transmitter Module, check the position of switch S5 for the correct frequency. Release push-button “SL”.

5.6.6 Restore Transmitter Module to Normal

1. Turn the power “OFF” at the Power Supply

Module.

2. Remove the 50, 75, or 100Ω resistor termina-

tion and replace the coaxial cable connection to the Line Tuner.

3. Move the Selective Level Meter to test jacks

marked “LINE” (on the RF Interface control panel):

• TJ1 (Line)

• TJ2 (Common)

4. Turn the power “ON” at the Power Supply

Module.

5. On the RF Interface Module, configure output

impedance by setting a jumper. The Selective Level Meter (TJ1, TJ2) should show a maximum reading (Vrms) for 1W (+30 dBm) power, as follows:

JU4 When set, provides 50Ω (7.07Vrms)

JU3 When set, provides 75Ω (8.6Vrms)

JU2 When set, provides 100Ω (10.0Vrms)

6. If the above (Vrms) values are not achieved, recheck the tuning of the coupling system, as it is not presenting the Transmitter with the proper termination.

5.7 Check TCF–10B Receiver

Margin Setting using Remote Carrier Signal

1. At the Power Supply Module, turn the power “ON”. If the frequency is not already set, refer to section 5.1.2.

2. Arrange for a received signal from the remote end,

3. Sensitivity setting:

On the Receiver module to complete the setting:

a) Hit “SET” twice until the display reads

“SET SENS?”

b) With the remote signal being received (at

the remote end, push the “LL button on the keying module), depress “SET” again.

c) If you’re not adjusting the 15 dB margin,

depress “SET” again. If you are, then depress “RAISE” or “LOWER” as required to adjust it up or down 5 dB.

d) If you are not going to adjust an external

carrier level meter, depress “SET”. Otherwise, press “RAISE” or “LOWER” as required.

4. Set the external CLI.

Once you have completed the sensitivity setting, the display scrolls this message: "Set Ext CLI? – Hit Raise/Lower or Set when done...”

To calibrate the external CLI push the CANCEL/RAISE or LOWER button. The external CLI meter will move up and down accordingly. The external meter is a 100µA instrument. If it is calibrated in µA, the meter should be set to read 67µA (this is equivalent to 0 dB on the internal meter). The setting should vary 3.3µA for each dB the margin adjustment has been raised or lowered from the 15 dB margin. If the meter is calibrated in

December 2004 Page 5–7

Chapter 5. Installation/Adjustment Procedures

NOTES:

1. The foregoing procedure adjusts the Receiver margin to the recommended 15 dB value.

2. The Receiver bar graph CLI meter reading should be 0 dB at this time.

3. In three-terminal line applications, the margin adjustment procedure should use the weaker of the two received signals.

4. When applying the TCF–10B with a phase comparison relay, do not readjust the Receiver level when keying with a square wave signal. The CLI will read around -10 dB, but this is an average reading of the on and off square wave. The receiver will still maintain the 15 dB margin. The CLI reading is only accurate for a non-amplitude modulated signal.

dB, set the meter to read equal to the internal CLI meter.

To accept the displayed level, push the SET button.

This completes the Receiver setting procedure.

5.8 Prepare the TCF–10B for Operation

Be sure that power is “ON” at the Power Supply Module.

1. Restore the Keying Module to the desired settings. (See the TCF–10B Adjustment Data Sheet near the end of this chapter. This data sheet is to be completed by your settings department.)

2. Replace the cover on the TCF–10B control panel.

a) Secure the latch by pushing inward and sideways until the cover is secure.

b) You may lock the latches into place using meter seals.

This completes the “Routine Adjustment” procedure. The TCF–10B is ready to be put into operation.

7.1 Preliminary Checks

7.1.1 Checking the Chassis Nameplate

Verify that the proper dc supply voltage and module options are on the chassis nameplate. Also, check for narrow, wide, or extra wide band; Phase Comparison or Directional Comparison (2or 3-Frequency).

Check to ensure that all required modules are supplied and are installed in the proper chassis slots. The slots are labeled on the top edge of the chassis.

7.1.2 Inspecting for the Correct dc Voltage

With the power “OFF,” remove the Power Supply module and inspect it for the correct dc voltage, as specified in Table 7-1.

7.2 TCF–10B Preliminary Connections

1. Refer to the Block Diagram (see Chapter 6,

Signal Path) for keying and output connections.

2. Connect the dc supply to the appropriate

terminals on the Rear Panel (see Figures 3-1 and 3-4, in Chapter 3, Installation).

3. Terminate the Transmitter output with a non-

inductive 50Ω, 25W resistor.

4. Connect the Selective Level Meter (Rycom

6021A) across the 50Ω resistor load.

It is not intended to perform the design verification tests at installation. If you need to verify the design of the TCF-10B, you should perform the following design verification test.(See Test Equipment in Chapter 4, and Signal Path in Chapter 6) otherwise, see chapter 5.

If the TCF–10B is a Transmitter (only) set, perform the following segments: 7.1, 7.2, 7.3, and 7.4. If the TCF–10B is a Receiver (only) set, perform segments 7.1, 7.2, 7.5, and 7.6. If the TCF–10B is a Transceiver set, perform segments 7.1, 7.2, and 7.7.

7.4.1 Power Supply Module Tests

Remove all modules except power supply.

1. Turn “ON” dc power. Both LEDs (D3, Input

and D11, Output) on the Power Supply Module should be “ON”. Measure dc voltage at Power Supply test jacks:

• TJ1/TJ2 (+20 Vdc ± 1 Vdc)

• TJ3/TJ2 (-20 Vdc ± 1 Vdc)

If the voltage is not within the above limits, do not proceed further. Have the power supply repaired or replaced.

2. Turn “OFF” the dc power. The Input LED

(D3) should be “OFF”.

3. Place the current meter (Simpson 260 or

equivalent) in series with the input dc supply and check the current for the appropriate voltage source, according to the specifications in Table 7-2:

4. Vary the input dc voltage to the minimum and

maximum levels per the following chart:

6. Return to nominal dc voltage.

7.4.2 Transmitter Tests

Input/Output Levels

Use the Selective Level Meter to measure levels per Table 7-3. If the 10W PA input level is not within limits, place the Transmitter module on an extender board (see Figure 4-1), and make the adjustments with controls per Table 7-3.

Transmitter Frequencies

Monitor the output frequency of the XMTR with the Selective Level Meter. If this frequency is incorrect by > ± 10 Hz, adjust the unshifted frequency with C19 (on the Transmitter module) to 250 kHz (or the required frequency) ± 1 Hz.

Use the “SH” and “SL” buttons on the Keying module to shift the output frequencies. The shift should be in accordance with Table 7-5 (within ± 10 Hz).

If the shifts are incorrect, set the shift (with S5) on the Transmitter module.

Observe the module LEDs shown in Table 7-4 below:

Chapter 7. Design Verification Tests

7.6.3 Frequency & Sensitivity Setting

To change settings on the FSK receivers, complete the following sequence:

1. Push the SET button.

This causes the frequency display to begin flashing, indicating that the receiver is in the “setting” mode.

If you do not touch any of the buttons for approximately three minutes, the receiver exits the setting mode and reverts to the previous settings.

2. Set the frequency.

To keep the displayed frequency, press the SET button again.

To increase the frequency, push the CANCEL/ RAISE button; to decrease it, push the LOWER button. Pushing either button once and releasing it raises or lowers the frequency by the minimum increment, 0.5 kHz. Holding down either button for more than two seconds increases the incrementing speed. If you exceed the maximum of 535 kHz, the display rolls over to the lower end, 30 kHz, and continues scrolling.

After you have the desired frequency displayed, release the button. The display once again flashes, indicating that it is still in the “setting” mode and has not yet accepted the new setting. Press the SET button to accept the frequency setting.

3. Set the sensitivity.

After you set the frequency, the display scrolls this message: "Set Sens?… – Hit Set or Cancel…".

To keep the current sensitivity setting, press the CANCEL/RAISE button.

To tell the receiver to automatically set the sensitivity based on an incoming remote signal, press the SET button. This sets the receiver for a 15 dB margin and calibrates the CLI meter to 0 dB. While the receiver is setting the sensitivity, the display scrolls the message: "Working…"

At first the bar graph is blank. Then it gradually ramps up until it reaches approximately 0 dB.

The display then tells you whether the sensitivity level is okay or if there is a problem, such as a signal too weak to set for a minimum pickup level.

After the display gives the "–OK–" message, it then scrolls the message "Sens Adjust? – Hit Raise/Lower or Set when done...” Here, you can either accept the current setting or manually adjust the receiver sensitivity.

To accept the current setting, press the SET button. The receiver is now set for a 15 dB margin, and the CLI reads approximately 0 dB.

To manually adjust the receiver sensitivity up or down 10 dB, push the CANCEL/RAISE or LOWER button. The CLI will track accordingly and remain at that level to indicate the sensitivity is set that much below or above the 15 dB setting.

Sometimes the incoming signal may not be strong enough to raise the margin the full 10 dB. If this happens, the display says "Warning: signal too low for more gain - hit Set to continue.." When this happens, push the SET button. This lowers the sensitivity to an acceptable level and flashes the bar graph to remind you that you are still in the “setting” mode.

To accept the displayed level, push the SET button.

4. Set the external CLI.

Once you have completed the sensitivity setting, the display scrolls this message: "Set Ext CLI? – Hit Raise/Lower or Set when done...”

To calibrate the external CLI push the CANCEL/RAISE or LOWER button. The external CLI meter will move up and down accordingly. The external meter is a 100µA instrument. If it is calibrated in µA, the meter should be set to read 67µA (this is equivalent to 0 dB on the internal meter). The setting should be varied 3.3µA for each dB the margin adjustment has been raised or lowered from the 15 dB margin. If the meter is calibrated in dB, set the meter to read equal to the internal CLI meter.

To accept the displayed level, push the SET button.

This completes the FSK setting procedure.

Receiver Logic Module

Place the Receiver Logic Module on an extender board and set the input signal to 250 kHz, or the required frequency, at a level of 112 mVrms, making sure the carrier level meter reads 0 dB.

To test the Phase Comparison Units (Only), complete the five steps depicted in Table 7-9.

To test the 2-Frequency Directional Comparison Units (Only), complete the 11 steps depicted in Table 7-10.

To test the 3-Frequency Directional Comparison Units (Only), complete the six steps depicted in Table 7-11. Use an input frequency of 250 kHz or the center frequency.
