Airborne Acoustic (AA)
Detect airborne acoustic Partial Discharge (PD) signals
Our Range of AA Sensors Enables Detection of Airborne Acoustic Signals From Corona, Surface Discharges and Tracking in Air Insulated Switchgear (AIS)
This compact ultrasonic sensor has an acoustic pickup designed for the detection of acoustic energy propagating through air. The sensors can be installed permanently during a planned outage or at the build stage of a project to enable On-line PD monitoring or routine spot testing. A temporary or permanent installation of AA sensors can be carried out without an outage if there are air vents or openings in the switchgear housing.
The AA Lite Sensor Is Magnetically Attached to the Outer Surface of Metal-clad Switchgear, Over Air Vents
It is then connected to the HVPD Kronos® Lite.
