Due to
the larger distances involved ultrasonic surveys on high power voltage lines
the sensitivity of the instrument is enhanced by using a parabolic signal
concentrator ultrasonic testing is extremely valuable for inspections of highvoltage electrical systems (above 2,000V). It is essential that these systems have
properly functioning insulation systems.
Failure of these systems can result in
catastrophic faults. Deterioration of high voltage insulation produces an electrical
leakage known as corona or partial discharge. This condition causes ionization
of the surrounding air. The ionization process produces ultrasound which is easily
picked up by our ultrasonic equipment allowing for speedy remeadial works and prevention of down time.
