Unified Algorithm Based on Rotating Phasors for Accurate Detection of Inrush Currents in Three-Phase Transformers

IEEE Access
The detection of inrush currents is vital for transformer differential protection. The mainstream method for detecting inrush current is based on the second harmonic content of the differential current.

Sympathetic inrush currents in transformer energisation

, 2018
Power transformers are critical components of the electricity networks. It is common knowledge that transformer energisation causes a number of slow-front inrush current transient problems. With the increase of distributed generations with inherent high intermittency resulting in more switching events, the transformers in service are increasingly ...
