The MK-720 is hand-held, battery-powered device designed to detect Electrical Arcing & Corona Discharge conditions --- without contact! Corona Discharge occurs when there is a problem with disconnectors, circuit breakers, insulators, etc leading to losses and potentially dangerous conditions. The MK-720 uses a proprietary algorithm to isolate the ultrasonic sound waves associated with Corona Discharge, separating it from the background noise performed, measured while the line is powered (hot). This algorithm significantly reduces the likelihood of false positive detection common with typical Ultrasonic Leak Detectors.
A large backlit LCD faces the user provide visual and audible indicators. A earphone is provided as part of the standard delivery helping the user to hear the audible tone alerting to the presence of Corona Discharge.
It features an over-sized ultrasonic receiver providing excellent range along with a focus with measurement in ±8° spot. It also features a laser pointer helping the user to visibly identify the target at all times.
Broadband ultrasound is emitted with corona discharge due to insulation deterioration at AC powered facilities. Since the intensity of the emitted ultrasound varies periodically with alternative voltage, double frequency components of power-supply appears prominently in frequency analysis after envelope detection of the received ultrasonic wave. MK-720 can detect corona discharge without effects of ambient noises by evaluating the intensity of double frequency components of the power-supply.
