Ultrasonic directional microphone for the location of partial discharge HV Diagnostics AG

Ultrasonic PD Sensor LDA-5/S used for PD detection during in-service inspection of high voltage (HV) equipment

Applications
Detection of partial discharges (PD) for in-service inspection of high voltage (HV) equipment, such as HV transmission lines, power transformers and gas insulated switch gears (GIS)
Interpretation of the acoustic emission (AE) with measuring frequencies about 100 kHz
Combined with electrical PD detection, the AE technique represents a cost-effective procedure for PD fault location
