3.7 Working With Test Plans
The CT-8000 comes with the Vanguard Circuit Breaker Analysis PC Software that can be used to
create circuit breaker test plans. The test plans can then be transferred to the CT-8000. The CT-
8000 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.
