Abstract
MAGNETIZING INRUSH CURRENT experienced when energizing a transformer has always presented a problem in the application of differential relays. The inrush current appears to the differential relay as a fault within the transformer and will cause the relay to operate and trip the transformer circuit breakers incorrectly. This problem is increased with the use of large transformers.
