摘要：

Fault diagnosis in electric machines can be accomplished by analyzing the anomalies in magnetic leakage flux. In order to achieve a desired performance from the leakage flux-based fault diagnosis approaches, an accurate monitoring system and a suitable algorithm are required. In this paper, a high precision Rogowski search coil is utilized for accurate monitoring of electric machine leakage flux. In addition, a simple fault diagnosis technique based on harmonic content of the measured signal is suggested. Performance of the technique is evaluated by some experiment tests.
