Internal Winding Fault Protection for Shunt Reactors

2011
Aleksandrs Dolgicers, Dmitrijs Antonovs

Existing protection techniques for shunt reactors can’t guarantee sufficient sensitivity for inter-winding faults due to limited precision of current transformer. To solve this usage problem of input resistance of resonance contour formed by reactor bank inductance attaching wiring capacitance is proposed. Difference between input resistance profiles of damaged and healthy bank is used as a fault criterion.
