Summary

IEC 61557-11:2009 specifies the requirements for testing equipment applied to the testing of the effectiveness of residual current monitors (RCMs) of type A and type B, which are already installed in distribution systems. This test equipment can be used in any kind of network like a TN, TT or IT system. The test equipment may also be used for testing directionally discriminating RCMs in IT-Systems.This part is to be used in conjunction with IEC 61557-1:2007, Part 1: General requirements.
