Ex87 - External Differential Protection
Available elements:
Ex87
All elements of the external differential protection are identically structured.
By means of these elements, the protective device can detect and execute pickups and trips that are issued by other
external devices. This can be helpful, for logging purposes, if the other device is not equipped with an event or
waveform recorder. This might also be helpful if the other device has no communication (SCADA) interface.
