Highly sensitive electro-acoustic pinpointer for locating underground cable faults

Kamphone N, Highly sensitive electro-acoustic pinpointer for locating underground cable faults

The pinpointer Kamphone is designed to locate flash-over faults in underground cable networks of various voltage levels accurately. It effectively measures the discharge noise and magnetic field that develop during the discharge of a fault in the ground. The flash discharge is usually generated by a suitable surge voltage generator. The point of max. signal strength will indicate the precise location of the fault.

Advanced evaluation features such as coincidence and time difference modes plus various background noise filter settings improve the location procedure substantially. The Kamphone device includes a receiver and a sensor unit. A wide range of coupling accessories allows adopting the sensor to different ground conditions.
