The Study of Using Ultrasonic Sensors to Detect Degradation Characteristics of the Ferrite Core

Abstract:

Severe temperature changes on electrical devices which are used ferrite cores causes very little degradation inside the core. In this paper was done to find out the size of the piezoelectric vibrator size and the most appropriate frequency In order to detect the degradation characteristics of the ferrite core. In this experiment, the frequency was used 1MHz,2.35MHz,5MHz, and the vibrator size was used 0.25inch,0.375incn,0.5inch. And the time axis variation was measured.
