Discrimination between an internal fault and a magnetizing inrush current has long been recognized as a challenging power transformer problem. This paper presents a new method of detection of inrush and fault current considering current waveform and its magnitude and time samples as ADC emulated data...
A new principle of discrimination between inrush current and internal fault current of transformer based on self-correction function When differential protective relays are applied to transformer protection, how to identify the magnetizing inrush current and short circuit current caused ...

The meaning of TRANSFORM FAULT is a strike-slip fault that occurs typically between segments of a mid-ocean ridge or other tectonic-plate boundary and that is characterized by shallow high-magnitude earthquakes.
By comparing the magnitude and duration of the external fault occurring on the transformer with DGA, the direct impact between the through fault current and the abnormalities of the transformer can be found. It is used to analyze, evaluate and provide appropriate treatment for the transformer. In...
