| 摘要 |
The invention consists of a relay device and corresponding method. The device comprises a mode change device (106) that changes the relay device (100) mode from a normal (N) to test (T); an interface (I/O) for receiving test script from a source (106); a waveform generator (208) for running the test script and outputting test results, the source (106) signals the relay (100) to switch modes (N, T); logic device (204) provides output to the waveform generator (208) during test mode; data preparation component calculates current and voltage samples from power system input (202); data preparation component calculates current and voltage samples from power system input (202); and a data processor (209) performs protection calculations (211) to determine an output of the relay.
