The Pin-pointing equipment is a directional acoustic listening device for the pinpointing of flash-over faults on power cables. State-of-the-art technology and ease of handling enables even users without training to precisely locate cable fault in conjunction with a surge generator (thumper).
The pin-pointing equipment measure the signals received by specially developed magnetic and acoustic sensors, which are integrated in one housing.
The trace of the buried cable can be determined by the direction and the intensity of the magnetic field, produced by the impulse current of a surge generator (for example, HDBM-30/4).
The acoustic locating is done by measuring the flash-over noise. A switchable filter is built-in to optimise the measurement. A coincidence measurement is possible by receiving and indicating the signals of both sensors simultaneously.
