Abstract
What is BS EN 61557-11 - Effectiveness of residual current monitors (RCMs) test about?
BS EN 61557-11 is a British Standard. BS EN 61557-11 is a part of the IEC 61557 series that specifies the requirements for testing equipment applied to the testing of the effectiveness of residual current monitors (RCMs) of type A and type B. Also, it is already installed in the distribution system. BS EN 61557-11 provides guidelines for safety requirements of electrical measurement and control to manufacturers and users. This test equipment can be used in any kind of networks like a TN, TT, or IT system. The test equipment may also be used for testing directionally discriminating RCMs in IT-Systems.
Who is BS EN 61557-11 - Effectiveness of residual current monitors (RCMs) test for?
BS EN 61557-11 on effectiveness of residual current monitors (RCMs) test is useful for:
