Title :
Electromagnetic interference effects due to line reactor coil-to-coil short circuits
Abstract :
The effect of coil-to-coil shorts on the impedance of line reactors has been an electromagnetic interference (EMI) safety issue for a number of years. This paper presents a comprehensive theoretical and experimental treatment of this issue. A circuit model was developed to evaluate the effects of coil-to-coil line reactor shorts. The circuit model was validated with experimental data. Potential failure mechanisms for coil-to-coil short circuits were developed and analyzed. Worst case values for potential shorts were established from experimental data. The system level effects for coil-to-coil short circuits were considered.
