Advanced Relay Testing and Transient Simulator (ARTTS) interface provides the bridge between the relay-testing hardware and power system simulation technology. The ARTTS interface provide the means to obtain the actual operation of protective relays based on steady-state and dynamic transient waveforms and compares the captured relay response with that of manufacturer published curves.
