Testing of the autoreclosure function with integral fault model
Configuration of the test sequences for the autoreclosure (AR) function of protection relays is both effective and time saving. Autoreclosure automatically sets up test conditions for successful and unsuccessful sequences. Essential criteria, like the three-phase final trip at the end of an unsuccessful sequence are automatically evaluated as well.
Overcurrent, distance, or line differential relays with autoreclosure function can be tested. The faults are specified by entering the fault type and fault quantities. This is supported by the integrated Fault Calculator which calculates the output voltages and currents for the different fault types. For testing the autoreclosure function of distance protection, the fault can be specified in the impedance plane.
The test sequence is displayed over time and a list of events with assessments is reported.
