ETAP tools > ETAP Advanced Relay Testing & Transient Simulator (ARTTS)
The ETAP Advanced Relay Testing and Transient Simulator (ARTTS) is a new concept that utilizes hardware and software technologies for testing, calibrating, and simulating relays.
ETAP ARTTS combines the short-circuit and protection device coordination capabilities of ETAP with the relay testing hardware. It provides actual steady-state and transient responses of relays for comparisons with the manufacturers published data. ARTTS is designed to improve system protection, coordination, and reliability, hence decreasing operational and maintenance costs.
ARTTS provides the bridge between the relay-testing hardware and power system simulation technology. While ETAP Star provides a revolutionary method of analyzing and simulating the protective device coordination and protection view via an intelligent one-line diagram, ETAP ARTTS determines 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.
