For most types of on-load tap changers (OLTC), the working medium is insulation oil in which the acoustic wave being formed propagates to the steal tank. There exists a possibility to register acoustic emission (AE) signals with different types of sensors. AE signal obtained in such manner contains information, which describes operation of the OLTCs power tap changer and the selector.
