Ponovo PW41i Protection Relay Test Set Three-phase Relay Protection Tester
 

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.
