PULSED ULTRASONIC SIGNALS PROCESSING WITH ACTIVE VIBRATION CONTROL OF ELECTRIC POWER EQUIPMENT
Abstract and keywords
Abstract (English):
The possibility of using pulsed ultrasonic probing for problems of vibrodiagnostics of electric power equipment is shown. The scheme of the measuring device is presented and described. A new algorithm for signal processing is proposed to control low-frequency vibrations. It is based on an analysis of the change of the cross-correlation function’s shape.

Keywords:
ultrasound, vibration control, electric power equipment, correlation processing, spectral analysis
