Abstract

PURPOSE: To detect the looseness of the winding for an electric apparatus by applying large current surge to the winding and detecting the vibration peak value, vibration frequency and vibration attenuating rate occurred at the winding at that time to process the detected signals.
CONSTITUTION: Large current surge generated from a large current surge generator 1 such as a charging and discharging capacitor or the like is flown through the winding terminal of an electric apparatus 2. A vibration detecting terminal 4 is disposed at the winding 5 of the apparatus 2 to produce a signal through an amplifier 9 to a signal processor 10. The signal processor 10 comprises a peak detector 10a, a vibration attenuation calculating circuit 10b and a frequency calculating circuit 10c. The output signal from the signal processor is displayed on an indicator 11.
