Earth Leakage Relay With Cbct

Installation procedure for earth leakage relay cbct.

Earth leakage relay with cbct.

An earth fault relay connected to the secondary winding is energised only when there is residual current in the primary system. Earth leakage relay with inbuilt cbct 300ma fixed elctr35 1 300ma 230v. Prok dv s make static earth leakage relay elr with core balance current transformer cbct zct are used to detect the leakage current in an electrical power system. Earth leakage relay elr can detect if the cbct zct connection status ie detecting the cbct zct open to ensure the healthiness of the relay.

Of the elr and cbct are matched. Of the elr and cbct should match for better performance the performance shall be guaranteed if the serial no. The earth leakage relay elr has back lit lcd display 2 line 8 character for displaying the nature and magnitude of fault. Earth leakage relay with inbuilt cbct 30ma fixed elctr35 1 30ma 230v.
