High-Frequency/Ultrasonic Noise Inspection

Energized electrical equipment is normally silent, with the exception of the steady 60Hz hum of a transformer. Even where electrical failure is imminent, there is very often no audible indicator of this pending failure.

Airborne Ultrasonic Detection represents another tool geared towards the detection and identification of approaching electrical failures.

High-frequency (ultrasonic, about 40kHz) noise can be generated by damaged or failing components in switchgear, transformers and overhead high-voltage systems. Using an ultrasonic translator we can seek out this high-frequency noise, providing an opportunity to address the problem before failure occurs.

Because ultrasonic frequencies can slip through the smallest openings, ultrasonic detection provides the means to safely identify issues even where access is severely limited (such as enclosed medium voltage switchgear).
