CT RATIO SELECTION FOR REF RELAY SETTING
In this video we have explained calculation of CT ratio for restricted earth fault relay setting calculation. These calculations are required for successful implementation of Restricted Earth fault protection of alternator and Transformer.
Restricted Earth Fault Protection is also known as differential earth fault protection. It is basically earth fault protection but works on differential relay principle.
Restricted Earth Fault Protection is used to detect earth fault inside a machine in general.
