  • Abstract
    Partial discharges in transformers cause high frequency (ultrasonic) pressure pulses to propagate through the insulating media. These are similar in character to stress waves propagated in solids during crack formation (acoustic emission). The techniques involved in the detection of acoustic emission (AE) are shown to be well suited to the detection of emissions from partial discharges.
