Protection Relay Testing and Commissioning

This is accomplished for inputs by applying known voltage and current inputs to the protection relay and verifying that the software has taken the correct values.

Protection Relay Testing and Commissioning

Digital and numerical protection relays typically need an auxiliary supply to give power to the on board microprocessor circuitry and the interfacing opto-isolated input circuits and output protection relays.
