Partial discharge detection microphone LDA-5/S

ultrasonicdirectional

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 Specifications Measuring frequency appr. 40 kHz Amplification > 80 dB Voltage supply 7,5 - 9,5 V Mean current consumption < 5 mA optional: Lasermodul available (current consumption appr. 80mA)
