Hi All,
Can you pl. give me an idea to test SIEMENS MAKE 7SN60-Transient ground fault relay by using numerical instrument?
Relay is detecting ground fault based on freq. signals (100 Hz to 1kHz or more). So, my perticular question is;
Transient ground fault is a pure high freq. signal without fundamental component for 1-cycle or it's a high freq. signal mixed with fundamental component? According to this, i need to create waveforms.
Normally relay is using for transmission line protection.
