Electrical Applications

Airborne ultrasound can be used to detect various electrical faults; including corona discharge, tracking, and arcing. The PowerBeam 300 parabolic accessory allows the technician to locate sources of ultrasound with pinpoint accuracy from distances up to 300 feet away. Additionally, the InCTRL platform and InCTRL mobile app can be used to record samples, store testing history, and communicate faults through a management chain. InCTRL's FFT spectral analysis feature can be used to diagnose recorded samples for electrical failures.

The UL101 Corona Detector (Part Number 000041)

The UL101 Corona Detector allows for early, long-distance detection of corona discharge, tracking, and arcing, reducing transmission loss and outages. The parabolic accessory (PowerBeam 300) can accurately pinpoint sources of ultrasound within 1 degree off center from up to 300 feet (91.44 meters) away. The Corona Detector does not include any other airborne attachments.

White Paper: Electrical Failure Diagnosis

Based on recommendations from ISO 29281-1, spectral analysis of airborne ultrasound will boost your decision-making capabilities when inspecting and detecting failures in electrical assets. The UL101 ultrasonic listening device (ULD) and the InCTRL cloud-based platform provide a friendly environment for reliable diagnosis and competent reporting.
