Custom Test Point

It is recommended that you follow these guidelines while defining the custom test points:

• Decimal values for the injection current are considered as invalid inputs.

• The value entered for the protection trip type must match to the protection setting being tested. For example:

  • In Short Time section, if you enter the value of injection current within the short-time current range, the MicroLogic trip unit will trip in short-time segment. This will indicate a Passed test status.

  • In Long Time section, if you enter the value of injection current within the long-time current range, the MicroLogic trip unit will trip in long-time segment. The test result may display the incorrect cause of the trip as short-time. During the test, as the circuit breaker has tripped within the expected trip time, the test result will indicate a Passed test status.
