2.1 Protective Relay
Applications Using
ON/OFF Carriers

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

• Directional-Comparison Blocking

• Phase-Comparison Blocking

• Current Only

• Distance Supervised

2.1.1 Directional-Comparison

Blocking

The basic elements for directional-comparison
blocking systems are shown in Figure 2-1a and
Figure 2-1b. At each terminal, the phase and
ground trip units (P) must be directional and set to
overreach the remote terminal; that is, they must
be set to operate for all internal faults. Nominal
settings of the distance units are 120 to 150
percent of the line. The start units (S) must reach
farther, or be set more sensitively, than the remote
trip units. Thus S

1 must be set more sensitively

than P

2 or reach farther behind bus G. Likewise,

S

2 must be set more sensitively than P1 or reach

farther behind bus H. In any case, the S and P
relays should be similar in type. If the trip unit (P)
is a directional overcurrent ground relay, the start
(S) ground relay should be a similar non-direc­tional overcurrent unit. The same principle applies
for the phase relays.

When the TC–10B ON-OFF power line carrier is
used with these schemes, except for possible
auxiliary functions, no signal is normally trans-
mitted, since the S units operate only during fault
conditions.

Operation of the directional-comparison scheme
(shown in Figure 2-1a and Figure 2-1b) is internal
faults. Subscript 1 indicates relays at station G for
breaker 1; subscript 2, relays at

station H for breaker 2. (Figure 2-1c shows a
solid-state logic version of Figure 2-1b.)

The schemes shown are still widely used for their
flexibility and reliability. Since the communica­tion channel is not required for tripping, internal
faults that might short and interrupt the channel
are not a problem. Over tripping will occur,
however, if the channel fails or is not established
for external faults within the reach of the trip fault
detectors. Since the carrier transmitter is normally
OFF, or non-transmitting, channel failure cannot
be detected until the system is tested or until an
external fault occurs. This limitation can be
overcome by using the optional TC–10B
checkback system with the TC–10B carrier.

2.1.2 Phase-Comparison Blocking

Basic elements of the phase-comparison systems
are shown in Figure 2-2. The system uses a
composite sequence current network to provide a
single-phase voltage output proportional to the
positive, negative, and zero sequence current
input. Sensitivity to different types of faults
depends on the weighting factors or constants
designed into the sequence current network.
Adjustments to the network are provided.

A squaring amplifier in the controlling relay
converts the single-phase voltage output to a
square wave. The positive voltage portion corre­sponds to the positive half-cycle of the filter
voltage wave and the zero portion corresponds to
the negative half-cycle. The square wave is used
to key the TC–10B, transmitting to the remote
terminal. The square wave from the remote
terminal is compared to the local square wave,
which has been delayed by an amount equal to the
absolute channel delay time. This comparison of
the local and remote square waves at each

terminal determines whether a fault
is internal or external.

Fault detectors are used to determine
whether a fault has occurred and to
supervise tripping. The fault
detectors must be overreaching, i.e.,
set sensitively enough to operate for
all internal phase and ground faults.

Because overcurrent fault detectors
are normally used, voltage trans­formers are not required. Such a
scheme is current only. Fault
detectors should be set above
maximum load, yet operate for all
internal faults. Distance fault
detectors, which require voltage
transformers, are used on heavy­loaded or long lines when distance
supervision is required.

2.1.3 Single Phase­Comparison
Blocking, Current
Only

In the current only system, the
TC–10B is used with two overcur­rent fault detectors (FD

l and FD

2).

FD

1, the carrier start unit, is set

more sensitively than FD

2 and

permits the local square wave
signal to key the “ON/OFF” carrier
transmitter. FD2, set with a higher
pickup than FD1, is used to arm the
system for tripping. For transmis­sion lines less than 100 miles long,
the FD

2

pickup is set at 125 percent

of FD

1. For lines longer than 100

miles, the FD

2 pickup is set at 200

percent of FD

1. On a three-terminal

line, FD

2 is set at 250% of FD1,

provided the line length between
any two breakers is less than 100
miles. Phase-Comparison cannot
occur until FD

2 operates. The

purpose of the two fault detectors is
to coordinate the comparison of the
local and remote square waves with
the keying of the carrier square
wave. The carrier must be started

before the comparison is allowed

to ensure that the remote square
wave has been received.

The basic operation of the system is
shown in Figure 2-3. FD

1

and FD2at
both terminals operate for an
internal fault (F

I

). The square wave
inputs to the AND from the local
currents are essentially in phase
with those transmitted via the
channel from the remote terminal.
The local square wave turns the
carrier “ON” and “OFF” to provide
the square wave receiver output for
the remote terminal.

A flip flop is energized if the inputs
to the AND continue for 4ms,
providing a continuous trip output

supervised by FD2 operation. The 4ms correspond to a phase
angle difference of 90°, on a 60-Hz base, between the currents at
the two terminals. The currents at the two ends of the line may
be out of phase by up to 90° and still trip. This is a blocking
system, since the receipt of a signal from the channel prevents
tripping. The carrier signal, therefore, does not have to be trans­mitted through the internal fault. No received signal puts a “1”
on the AND input. With the remote terminals open, this system
provides sensitive instantaneous overcurrent protection for the
entire line. As is characteristic of blocking systems, the channel
is not required for tripping on internal faults.

For an external fault, such as F

E in Figure 2-3, blocking is essen-

tially continuous, since the remote wave input to the AND is
out-of-phase with the local square wave. The secondary ct
currents are essentially out-of-phase for an external fault. The
currents can, however, be in-phase by up to 90

° on a 60-Hz base

and still block.

2.1.4 Single-Phase, Distance-

Supervised Comparison
Blocking

A distance-supervised scheme should be used
if the minimum internal three-phase fault
current is less than twice the maximum load
current. Twice maximum load current allows
FD

l to operate positively on the minimum

internal three-phase fault, yet reset when an
external fault is followed by a maximum load
current flowing through the line. The TC–10B
operates in the same manner as when used
with the current-only scheme, except for the
fault detection and arming techniques.

Two sequence current networks and two
distance relays supplement the two overcur­rent fault detectors.

One sequence current network responds only
to negative and zero sequence currents,
detecting all phase-to-phase and ground faults
(but not three-phase faults). The output of this
adjustable network operates the conventional
overcurrent FD

l and FD2

fault detectors. The
two distance relays operate only for three­phase faults. Thus, FD

2 provides the arming

function for all unbalanced phase and ground
faults, through the adjustable filter, and one of
the distance relays (21P) provides arming for
all three-phase faults.

The second and non-adjustable sequence
current network operates through the squaring
amplifier, providing the local square wave and
the carrier-keyed square wave required for
phase comparison. This signal is keyed by FD

1

and the second distance relay (21S) to provide
the carrier start functions. This second
network responds to positive, negative, and
zero sequence currents. Separate networks
provide greater sensitivity: with phase-to­phase faults, for example, more than twice the
sensitivity is gained.

|| 2.1.5 Phase Comparison Relaying

and 20V Auxilliary Power
Supply

|| When ordering a TC-10B for use with phase
comparison relaying, a 20V auxilliary 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 125Vdc,
then the carrier output will be powered up with
125Vdc 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 ener gy quickly,
to adhere to the timing requirements for a secure
phase comparison relay system, the use of the
auxilliary 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
auxilliary 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
auxilliary power supply for two reasons; decay
time of the energy, and the heating caused by the
dissipation of energy.||

Because the TC–10B is “ON/OFF” modulated,
only one frequency (f

C

) is required for line protec-

tion. When applied to three terminal lines, phase

cancellation will occur when two or more trans­mitters are keyed simultaneously. To prevent this,
you should offset transmitters by ±100Hz, using
the thumbwheel frequency programming
switches. The three frequencies should be:

•f

C

•fC- 100Hz

•f

C

+ 100Hz

When using the TC–10B with the SKBU-1 Phase­Comparison, you must offset the transmitter
frequencies from the center frequency by 100 Hz
for all applications. In a two-terminal application,
set the transmitter at one end 100Hz above the
center frequency, and the transmitter at the other
end 100Hz below the center frequency. Thus, the
two transmitters are spaced 200Hz from each
other. For a three terminal line, you should offset
the transmitter as described in the above
paragraph.

The TC–10B does not have an adjustable filter or
hybrid attached to the output of the transmitter.

If you are using the TC–10B in an application
where no other power line carrier equipment is
attached to the power line, then no further action
is required. However, in the application of

Single Comparator Phase Comparison
relaying, the TC–10B is to be operated in the
four-wire mode (see RF Interface Module),
with an external skewed hybrid between trans­mitter and receiver.

If you are applying the carrier set with other trans­mitters, coupled through the same tuning
equipment, you must apply a hybrid or a series LC
unit to the transmitter output to isolate the other
transmitters from the TC–10B transmitter. This
will avoid the problems of intermodulation distor­tion. We suggest that you use a hybrid if the
frequency spacing between all transmitters is
within the bandwidth of the hybrid (usually 6%).
Check the manufacturers instructions for the
actual spacing limitations of the hybrid you are
using. If you cannot use a hybrid, then you may
use a series LC unit to isolate the transmitters. In
this case, the transmitters must have spacing such
that the LC you are using will attenuate the

external frequencies by at least 20dB (if the other
frequency is a 10 watt transmitter), and 30dB (if
the other frequency is a 100 watt transmitter).

2.3 Ordering Information

The TC–10B carrier is functionally compatible
with earlier type carrier equipment (e.g., KR, TC,
TC-10, TC-10A). That is, you may use the
TC–10B with these other carrier types at the
opposite end of the line, with or without voice
function. You may use the same telephone handset
unit with any of these ON-OFF carrier sets.

You may use the TC–10B carrier set with the
following types of relay systems:

• All Directional-Comparison Blocking
Systems

• Phase-Comparison Blocking Systems,
e.g., SKBU-1 (Requires 45-Vdc power

supply — please see Table 2-5.)

Simplified schematics of typical electro-mechan­ical systems are shown in Figure 2-5 through
Figure 2-13 (schemes A thru K). These schemes
indicate the different jumper positions required for
particular applications. Simplified connections
between the TC–10B and a microprocessor based
relay are shown in Figure 2-14 (Scheme L).

Figure 2-15 shows the output circuit for micro­processor based relays (1 amp maximum output).

Figure 2-16 shows the resultant output circuit for
48, 125, and 250Vdc systems.

Two variations of TC–10B are available:
(1) Plug-in Voice Adapter Module with signaling

as a push-to-talk maintenance voice channel ­(see Chapter 17). Atelephone jack is provided
on the Voice Adapter Module, but you may
also use a remote jack or hookswitch. (See
Figure 18-4, Scheme J, for the connection
diagrams.)

(2) Plug-in Universal Checkback Module for

periodic testing of the carrier channel at
programmable intervals (see Chapter 17).
(See Figure 3–3 for connection diagrams.)

The equipment identification number (catalog
number) is located in the middle of the front panel
(just to the left of the 10W PA Module). The
TC–10B catalog number comprises eight (8) char­acters, each in a specific position. This number
identifies the unit's technical characteristics and
capabilities, as well as any optional modules
installed in the unit.

Table 2-2 provides a complete listing of the
options for ordering a TC–10B, as well as a
sample catalog number. To order one or more
TC–10Bs, simply identify the features and
optional modules you want for each chassis. For
example, the typical catalog number shown in
Table 2-2 — S1A1WVAS— orders a
TC–10B with the following features:

Basic TC–10B Transmitter/Receiver
Power Output: 10 watt
Universal Checkback: Universal Checkback

Alarm and Carrier Level Indication: with loss-

of-dc-power alarm relay, R.F. output alarm
relay, received-carrier-level-margin alarm
relay, detect alarm, instrument indicating
carrier level (-20dB to +10dB), carrier level
analog output (0–100 µA) for external instru­ment

Outputs: Dual transistor-switched outputs (for

use with electro-mechanical carrier auxiliary

Table 2-3 provides a further breakdown of the
TC–10B catalog number by style numbers.

The accessories available for the TC–10B are
listed, along with their style numbers, in Table 2-4
and Table 2-5. To order an accessory, simply give
its style number.
