PMDT 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
