PW41i Protective Relay Test Set PW41i is a reliable protective relay test set with high current output (3×40A) and high voltage output (4×300V‐advanced version or 3×300V‐ standard version). It is with built‐ in local system so that the testings could be done easily by the relay test set itself. The PW41i advanced version also can be connected to external PC via PowerTest relay test software running to do testing as well. PW41i is a favorable and economical testing solution for commissioning work in distribution grid. More Options for Different Testing Requirement  PW41i‐standard version,...
