INSTALLATION PROCEDURE FOR EARTH LEAKAGE RELAY CBCT :
- Check the sensitivity of Earth Leakage Relay and also the inner diameter of core balance current transformer.
- The Serial No. of the ELR and CBCT should match for better performance (the performance shall be guaranteed if the serial no. of the ELR and CBCT are matched).
- Check the Auxiliary Supply of ELR and proper Voltage i.e. the rated Auxiliary Voltage.
- The ELR have one pair of potential free change over contact for tripping purpose. Use rated current and rated voltage (refer the specification of our product). One pair of change over contact i.e., N/O Contact and N/C Contact can be used depending upon the tripping management.
