摘要：
A new stator ground fault protection scheme is introduced in this paper. It is based on wavelet transform, particularly the multiresolution analysis (MRA) technique. The effectiveness of the proposed scheme was verified both in the experiment and in the field, Investigation results show that the scheme can detect the ground fault with high sensitivity and selectivity during all operating conditions.
