Partial discharge detection microphone / ultrasonic / directional

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

Amplification > 80 dB
Voltage supply 7,5 - 9,5 V
Mean current consumption optional: Lasermodul available (current consumption appr. 80mA)

Specifications

  • Applications: for partial discharge detection
  • Technology: ultrasonic
  • Other characteristics: directional
