Ground fault monitors
Ground fault monitors
(OP)
Specialised relay vendors supply CBCT and the Ground fault monitor relay as a package. The relay settings are sensitive in terms of primary current directly and no CT ratio etc. details are to be provided as input to the relay. No issue.
For sensitive earth fault protection, normally I am used to seeing a low CT ratio but here I find the CT ratio to be 600/1A while the setting range is 3mA to 16A.
Appreciate if some one could help my understanding the above. Thanks.
