Acoustic Contact (AE)
Ultrasonic Contact Probe (20kHz - 300kHz) The ultrasonic contact probe is ideal for detecting and localizing partial discharges in fluid dielectrics such as oil and SF6 gas compartments. This is sometimes called “in-tank” testing. Each time a PD event occurs, an ultrasonic emission is produced at the site of the defect. If the defect is inside of sealed equipment such as a transformer or SF6 compartment, then the signal will (usually) not become airborne.
