Distance Relay Test

If you need to test a fault distance relay, you have to understand line impedance, zones of protection, and fault characteristics first. The relay is usually set to pick up based on an impedance value (fault current & voltage at some specific angle to each other) that you need to calculate.

Once you know the fault values that the relay is expecting to see, then you need the test equipment to be able to inject the appropriate I & V, and time the relay's response.
