REV 1 CT-7000 S3 USER’S MANUAL

1.0 INTRODUCTION

1.1 General Description and Features

The CT-7000 S3 is Vanguard's fourth generation EHV circuit breaker analyzer. The CT-7000 S3 is available with 3 (part number 9021-UC) or 6 contact timing channels (part number 9100UC).The CT-7000 S3 can fully analyze a circuit breaker's performance by measuring the main contact and resistor contact time, stroke, velocity, over-travel, bounce back and contact wipes. Both contact and motion analysis can be performed on all circuit breaker operations (OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN, and OPEN-CLOSE-OPEN). The CT-7000 S3's timing window is selectable between 1 second, 10 seconds, and 20 seconds.

Contact Timing Input Channels

The CT-7000 S3's dry contact timing channels (up to 6 channels) are used to time the circuit breaker main contacts. Each main contact timing channel is capable of detecting the main contact and insertion resistor contact time. Timing results are displayed in milliseconds and cycles.

Breaker Stroke and Velocity

Three dedicated digital travel transducer channels are available on the CT-7000 S3 for measuring circuit-breaker contact stroke, velocity, over-travel, and bounce back. With the use of the Vanguard digital travel transducers, neither calibration nor setting is required. Circuit breaker contact velocity is calculated based on contact’s travel distance over a period of time. Special formulas to calculate velocity is also accommodated by the CT-7000 S3. Special feature is also available to “Slow-Close” test the circuit breaker and obtain a test result report.

Resistor Type Transducer Inputs

The CT-7000 S3 offers 3 resistor type transducer input channels. These input channels are used to interface with any resistor-type transducer to monitor the circuit breaker motion. Transducer resistance ranges from 200 Ohms to 10K Ohms.

Voltage Monitoring Channels

The CT-7000 S3 features three voltage monitoring input channels (V1, V2, and V3). The V1 voltage channel is dedicated to monitoring the substation DC supply or coil voltage (0-255 V, DC or peak AC). The nominal and minimum DC supply voltage levels are recorded and printed on the tabulated report. An analog waveform showing the DC power supply is plotted on the graphical report. The two digital voltage input channels, V2 and V3, are dedicated to monitoring voltage on/off status presence or absence of the circuit breaker auxiliary switches. Digital waveforms showing V2 and V3 activity are plotted on the graphical report. Three timing events of the V2 and V3 activities are recorded and printed on the tabulated report.

CT-7000 S3 USER’S MANUAL REV 1

Breaker Initiate Features

A built-in solid-state initiate device is used to operate a breaker from the CT-7000 S3. Operational modes include OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN, and OPEN-CLOSE-OPEN. Multiple operation like OPEN-CLOSE, CLOSE-OPEN, and OPEN-CLOSE-OPEN can be initiated by using a programmable delay time (in milliseconds) or by sensing a specific breaker contact condition.

OPEN/CLOSE Coil Current Monitoring

One built-in, hall-effect sensor records the OPEN/CLOSE coil current amplitude and waveform. The circuit breaker’s coil current waveform, effectively, a coil performance “fingerprint” or “current profile”, can be used as a diagnostic tool for analyzing the circuit breaker’s performance.

Computer Interface

The CT-7000 S3 can be computer-controlled via the USB or optional Bluetooth interface. Windows-based Circuit Breaker Analysis Software is provided with each unit. Using this software, circuit breakers can be timed from the PC. Test records can be retrieved from the CT7000 S3 and then stored on the PC for future analysis and report generation. Circuit breaker test plans can also be created on the PC and transferred to the CT-7000 S3. Additionally, test records can be automatically exported in Excel, PDF, and XML formats.

Internal Test Record and Test Plan Storage

The CT-7000 S3 uses Flash memory to store up to 200 test records internally. Test records can be recalled and printed on the unit's built-in 4.5" wide thermal printer. Test records can also be transferred to a USB Flash drive or exported to a PC via the USB port or Bluetooth (optional) with the included Windows-based software. Up to 100 circuit breaker test plans can be stored in the CT-7000 S3's Flash memory. A test plan is comprised of all circuit breaker performance specifications (contact time, stroke, velocity, etc.). When a test plan is used with a timing test, a Pass/Fail report is generated by comparing the actual performance with the specifications in the stored test plan. Test plans can be transferred to the CT-7000 S3 from a USB Flash drive, or from a PC via the USB port or Bluetooth (optional).

External Test Record and Test Plan Storage

A USB Flash drive can be used to store and transfer test plans and up to 999 test records.

Built-in Thermal Printer

The CT-7000 S3's built-in 4.5" wide thermal printer can print the breaker contact analysis results in both tabular and graphic formats.

User Interface

The CT-7000 S3 features a back-lit graphic LCD screen (240 x 128 pixels) that is viewable in direct sunlight and low-light levels. A rugged 44-key "QWERTY"-style membrane keypad is used to control the unit and input information.

REV 1 CT-7000 S3 USER’S MANUAL

Diagnostic Capabilities

The CT-7000 S3 can perform diagnostics on its internal electronics. Diagnostics can be performed to verify contact cable connections and to test the travel transducer’s electronics.

1.2 Optional Features “On-line” Timing Mode

In addition to the conventional off-line timing mode, the CT-7000 S3 also offers an optional three-phase “on-line” timing mode. In this mode, the CT-7000 S3 captures the breaker’s trip or close time, the trip/close coil current “fingerprint”, and the battery supply voltage while the breaker is still in service. The trip/close time is derived from the time of trip, or close coil initiation, to the breaker’s bushing current breaker-make as detected by a AC clamp-on current sensing probes. Trip/Close current waveforms are also captured by an external clamp-on DC current probe.

The “on-line” timing mode can detect a breaker’s operating conditions with little or no down time. In this mode, the first trip operation time of the breaker is captured. If a breaker has been in service for a long period of time and sitting in close position, the first trip time of the breaker may be slow possibly due to a sticky mechanism. The “on-line” mode is very useful in such cases because traditional breaker timing may not detect this condition since several operations may have occurred before the first timing test is conducted.

Dual Ground Testing Mode

With the optional dual ground testing mode, the CT-7000 S3 can measure a CB contact time with ground being applied to both sides of the bushings. The clamp-on probe is connected to one side of the CB safety ground straps, and an AC signal is coupled to this strap. A sensor on the probe will detect a change in the induced AC signal when the CB contact is opened or closed.

Bluetooth Interface

The optional Bluetooth interface can be used to wirelessly connect the CT-7000 S3 with a PC.

3.1.3. Online Timing Connections (w it h optional Online Timing feature)

In addition to the conventional off-line timing mode, the CT-7000 S3 also offers an optional three-phase “on-line” timing mode. In this mode, the CT-7000 S3 captures the breaker’s trip or close time, the trip/close coil current “fingerprint”, the battery supply voltage, and auxiliary switch times while the breaker is still in service. The trip/close time is derived from the time of trip, or close coil initiation, to the breaker’s bushing current breaker make/break as detected by a AC clamp-on current sensing probes. Trip/Close current waveforms are also captured by an external clamp-on DC current probe.

The CT-7000 S3 On-Line timing mode requires the use of 3 AC current sensors (provided with the Online Timing Option, Part no. 9021-OT) to monitor the contact time phases A, B, and C. The Open and Close coil current is monitored by using the provided DC current sensor (provided with the Online Timing Option, Part no. 9021-OT). The On-Line timing mode requires the External trigger to be connected. Please see Figure 7 for the On-Line timing test connections.

3.1.4. Dual Ground Connections (w ith optional Dual Ground feature)

The CT-7000 S3 Dual Ground test mode requires the use of the Vanguard Dual Ground Current Probes (provided with the Dual Ground option, part no. 9021-DG). Up to 3 timing channels are available with the Dual Ground option. Only timing channels 1, 2, and 3 are used for this mode (see Figure 8).

Figure 8. Typical Connections for Optional Dual Ground Testing Mode

Transducer channels, voltage monitoring channels, and the initiate circuit are connected the same as the regular time travel test mode.

3.1.5. Analog and Digital Vo ltage Monitoring Connections

The analog voltage input “V1” can monitor a breaker’s DC control voltage during an operation. The analog voltage input records the nominal DC voltage at no load and the minimum DC voltage while the Trip or Close coil is energized. The nominal and minimal voltage readings are printed on a tabulated report, and the analog waveforms are plotted in graphical format. This allows the user to see the breaker’s DC control voltage “dip” under load conditions and helps detect problems such as a poor connection or an excessive voltage drop during operation. Please note that the maximum voltage that can be recorded is 250 Vdc.

The digital voltage input channels “V2” and “V3” can monitor the voltage status as “ON” or “OFF” states. The voltage “ON” or “OFF” states are plotted on the graphical report. Three voltage on/off events are also printed on the tabulated timing report. Typical analog (“V1”) and digital (“V2”) voltage monitoring connections are shown in Figure 9.

REV 1 CT-7000 S3 USER’S MANUAL

3.1.6. External Trigger Input Connections

The External Trigger Mode can be used to start recording data when the CT-7000 S3 senses a voltage. A typical application for the External Trigger Mode is to time a circuit breaker in a Close operation and to start timing only when the Close coil is energized, thus bypassing the 52X relay delay time.

Since the 52X relay carries the Close coil current, the CT-7000 S3’s initiate cable must be connected to the Close terminal as shown in Figure 4. The CT-7000 S3 will energize the 52X relay to start the Close operation, which will then start the timing when the CT-7000 S3 senses the voltage across the closing coil. Typical external trigger input connections are shown in Figure 10.

Another application for the External Trigger is to start timing the breaker when the user trips or closes the breaker remotely.

• The minimum trigger voltage is 30 Vac/dc. Maximum, continuous voltage is limited

to 300 Vac/dc. Different trigger voltages can be set at the factory by request.

NOTES

• The CT-7000 S3 will start looking for the external trigger voltage when the message

“AWAITING TRIGGER…” is displayed on the LCD screen. The external trigger voltage must be sensed by the CT-7000 S3 within 15 seconds after the initiate sequence has begun. The CT-7000 S3 will return to the “START-UP” menu if no voltage is sensed.

REV 1 CT-7000 S3 USER’S MANUAL

3.1.8. Resistor Type Transducer Con nection

The CT-7000 S3 provides three channels for resistor type transducers. The transducer resistance input can range from 200 Ohms to 10K Ohms. The CT-7000 S3 supplies a 5 Vdc reference voltage to power the resistor type transducer. The sense voltage is translated into a travel distance based on the transducer calibration parameters. The user is required to setup the resistor transducer before performing a test. Up to nine transducer setups can be stored in the CT-7000 S3’s internal memory. Once a transducer setup is stored, it can be recalled quickly before running a test. A typical resistor type transducer connection is shown in Figure 12.

• When a resistor type transducer is selected, all three resistor transducer channels

(R1, R2, and R3) are active and will be shown on the test results (see Figure 17).

NOTES

• A 15-foot transducer cable with 3 quick disconnect clips is provided with each CT-

7000 S3. The 3 clips are labeled “+5V”, “Signal”, and “GND”.

• See section 3.2.11 for resistor type transducer calibration information.

3.2.9. Configuring the Transducer Encoder Filter Setting

In a typical 1-second timing record, the CT-7000 S3 records 20,000 data points for each of the contact channels, digital transducer channels, voltage input channels, CT channel, DCR channel, resistor transducer channel, and initiate current channel. In most circuit breaker timing applications, the breaker activities end after 200 milliseconds. A common problem found in the field is that after the breaker activities have ended, the CT-7000 S3 may record erroneous data on the transducer channels due to vibration. The erroneous data may be due to the transducer not being secured properly to the mounting plate or due to a poor linkage problem between the transducer and the circuit breaker mechanism.

To address this problem, the CT-7000 S3’s transducer encoder filter setting can be used to stop recording the transducer channel data after a specific time. This feature can filter out the unwanted motion picked up by the transducer after the breaker activities have ended. The CT7000 S3’s default filter value is set to “No Filter” when the unit is powered on. Use the steps below to change the transducer encoder filter setting:

3.3 Performing Circuit Breaker Timing Tests

The CT-7000 S3 can initiate the breaker operation and perform a timing test on the following operations:

• OPEN

• CLOSE

• OPEN-CLOSE

• CLOSE-OPEN

• OPEN-CLOSE-OPEN

The CT-7000 S3 can start the OPEN-CLOSE operations without a delay or by using a programmable delay between the OPEN and CLOSE commands.

The CLOSE-OPEN operation can be started by the CT-7000 S3 using several options:

• Contact #1 CLOSE

The CT-7000 S3 can initiate a CLOSE command and then an OPEN command after detecting the closing of the breaker’s contact. The CT-7000 S3 detects the closing of the contact through contact channel #1. This option is recommended for the CLOSE-OPEN operation since it truly represents when the circuit breaker closed and then opened.

• Set DELAY

The CT-7000 S3 can initiate a CLOSE command and then an OPEN command after a programmable delay set in milliseconds.

• No DELAY

The CT-7000 S3 can initiate a CLOSE command and then an OPEN command without any delay. Since the circuit breaker is in the OPEN state, the breaker’s 52B contact allows the CLOSE coil to be energized, which can start the CLOSE command. When the circuit breaker is making the transition from an OPEN state to a CLOSE state, the 52A contact will close allowing the breaker to initiate the OPEN command.

The OPEN-CLOSE-OPEN operation can be initiated by the CT-7000 S3 by using a programmable delay between each of the operations. The delays can be set between the OPEN to CLOSE commands and between the CLOSE to OPEN commands.

CT-7000 S3 USER’S MANUAL REV 1

3.3.1. Timing an OPEN Operation

The CT-7000 S3 can time breakers with or without insertion resistors. The insertion resistance can range from 10 to 5,000 Ohms. Any insertion resistance greater than 5,000 Ohms is detected as an open circuit. The timing results will show the main contact time and the insertion resistor contact time. Graphic reports will show the main contact and the resistor contact activities on each of the channels. Use the steps below to time an OPEN operation.

a. When the unit is turned on and the firmware has been loaded, you will be presented

3.3.2. Timing a CLOSE-OPEN Operation Using Contact Channel #1

The CLOSE-OPEN operation of a breaker simulates a condition where a breaker is closed on a fault. There are three options when timing a CLOSE-OPEN operation:

1. Contact #1 CLOSE

The CT-7000 S3 will initiate a CLOSE operation. The open operation is then initiated after contact channel #1 is closed. This option closes simulates the breaker closing on a fault condition in the field.

2. Set DELAY

A delay from 10 to 500 ms can be set between the CLOSE command and the OPEN command. The CT-7000 S3 will initiate the CLOSE operation and start the delay counter. The OPEN operation will be initiated when the delay time has elapsed.

3. No DELAY

Both the CLOSE and OPEN commands are initiated by the CT-7000 S3 simultaneously. The OPEN coil is energized when the OPEN auxiliary switch makes.

3.5 Working With Test Plans

The CT-7000 S3 comes with the Vanguard Circuit Breaker Analysis S2 (VCBA S2) PC Software that can be used to create circuit breaker test plans. The test plans can then be transferred to the CT-7000 S3. The CT-7000 S3 can store up to 99 circuit breaker test plans in its Flash EEPROM.

A circuit breaker test plan contains breaker maximum/minimum parameters and can be used to quickly test a breaker. A typical list of operating parameters in a test plan includes the following:

• Max/Min Contact/Resistor Trip Time

• Max/Min Contact/Resistor CLOSE time

• Max Contact Spread Time

• Max Resistor Contact Spread Time

• Max/Min Contact CLOSE-OPEN Time

• Max/Min Contact OPEN-CLOSE Time

• Max/Min Resistor CLOSE-OPEN Time

• Max/Min Resistor OPEN-CLOSE Time

• Max/Min Breaker Stroke

• Max/Min Breaker Trip Velocity

• Max/Min Breaker CLOSE Velocity

• Max/Min Breaker Over-Travel

• Max/Min Breaker Bounce-Back

• Trip Velocity Analysis Calculation Points

• CLOSE Velocity Analysis Calculation Points

If a timing test is executed with a breaker test plan, the timing report will display a Pass/Fail indicator for each of the parameters tested. The Pass/Fail status is determined by comparing the values in the test plan to the timing test results.
