Partial Discharge Testing with an Acoustic Imaging Camera

Electrical Safety RiskOrigins of Electrical DefectsWhat Is Partial discharge?Partial Discharge EffectsWhere Do We Find Partial discharge?Any discussion about risk must include health and safety. But it should not ignore asset reliability. One certainty is that safety and reliability risks are both linked to unscheduled downtime, costly legal exercises, and ultimately, lost profit. A perfect solution identifies safety and reliability as one and the same and marginalizes their impact on the other three. Ultrasound is the best technology for reducing the risk of electrical arc flash exposure while ensuring equipment reliability. It does this by detecting defects which, when left to deteriorate, could lead to an arc flash event. This doesn’t suggest that ultrasound removes the need for personal protective equipment and other safety measures. Inspectors must still adhere to all safety protocols in place for working near electrical assets. The long-distance sonic imagery capabilities of the SonaVu™ acoustic imaging camera make it an essential tool for inspecting electrical systems for partial discharge while maintaining el...Get price
