PW41i Protective Relay Test Set  Rear Panel Power supply switch Power supply connector PW41i Local Relay Test Set Software PW41i is a type of relay tester controlled locally and externally by a PC. A color touchscreen and local control system make PW41i portable and easy to use. The local software embedded in PW41i is called PowerTestCut. There are 11 test modules in the software: Directional, Frequency Relay, QuickTest, Ramp, State Sequence, Time Inversed Current, Time Inversed Voltage, and Time. More powerful functions are available with Powertest's PC control.
