Discrimination of Inrush Currents in Differential Relays

This research addresses the critical challenge of accurately discriminating inrush currents within differential relays, a key component of power transformer protection systems. Differential relays distinguish genuine internal faults from transient events, such as inrush currents and external faults.

Magnetic saturation and inrush current in transformers

2008
The project aims to find a new method, used to discriminate between inrush current and short circuit current based on the waveform discrimination using neural network which is different from the conventional method using the ratio of second harmonic current to differential current.
