It is a receiver of acoustic shock waves and audio frequencies.
It is used to pin-point cable faults in power cables and installations and to trace the route of underground cables.
The RPF A / I receiver is a directional acoustic device for the pin-pointing of flash-over fault and on the same unit a receiver of electromagnetic frequencies for tracking traces. Its simplicity of operation allows users to accurately pin-point faults when used in conjunction with a surge generator like GIC model. In the audio-frequency receiver mode it allows to know the trace of underground cables and pin-pointing low impedance faults, when used in conjunction with an audio frequency generator, like RGT 100 model.
