Distribution protection relays have changed dramatically in the last decade from simple single function overcurrent protection relays into multifunctional IEDs with primary distribution feeder protection functions. Testing of such devices requires the availability of a set of tools that will simplify the testing process, while at the same time will ensure the required high quality of that testing process.
The paper analyzes the functionality of modern state-of-the-art distribution feeder protection relays.
