WebThe single grounding of current transformers eliminates the problems of the voltage generated at different ground points of the current transformer. According to IEEE C57,13.3-2014-IEEE Guidelines for grounding of instrument transformer. The secondary of the current and potential transformer must be grounded. WebJul 20, 2016 · This net mmf is the working / magnetizing mmf of the core of CT. Now, in case secondary winding is kept open then secondary current will be zero while the primary current of CT will remain same. Therefore the opposing mmf of secondary will no longer exist. Hence the net mmf is due to primary current only i.e. N1I1 which is very large.
