Recorded data from field Limitations• Open loop• Fixed V/I and ramp up• No data alteration/loss
This is a good and proven method for most “traditional” and “easy” cases

Simulator
Real-time simulators are used by advanced testing laboratories for complex cases and developing/testing new relay algorithms using new technologies…
Advantages• Closed loop• Detailed EMT simulation• Complex protection schemes• See effect of the relay on grid
…Enhanced by Using a Real-Time Simulator
