Tips: How to Prevent Current Transformer Burning up?

• Add a watchdog breaker and avoid the power failure of whole feeder line caused by faults on branches, particularly, ensure that the branch breaker can trip correctly in case of single-phase grounding at the user side.
• Connect the metering current transformer downstream the breaker, so as to guarantee that the breaker and lightning arrester operate correctly to remove faults when the transformer breaks down.
• Strengthen the flashing test for user’s high voltage metering current transformer and lightning arrester (it shall not be more than 4 years according to regulations), find out the aging degree of current transformer and lightning arrester insulation as early as possible, replace timely to avoid power failure caused by burning out of metering current transformer.
• Clean the user primary device regularly to reduce the occurrence of flashover, avoid insulation reduction.
