Abstract

In this paper the vibrational noise of a small scale laminated transformer core is measured to study the magnetic phenomena known as magnetostriction which generates its characteristic hum. Noise frequency measurements are recorded using traditional microphone arrangements and a highly sophisticated 2D acoustic camera array to trial its application. The recorded results examine the frequency harmonics of the transformer noise and analyze a method for specific frequency location detection.
