Locator S

Cable sheath fault pinpointer

The pinpointer Locator S is designed to locate cable (outer) sheath faults on shielded or unshielded plastic insulated cables accurately. It effectively measures step-voltage potentials in the earth that will develop during faults in underground cable sheaths. In combination with a suitable test generator (DC pulse or surge) the precise location can be detected offline. The Locator S consists of a digital voltage detector and two step voltage probes. After spiking the flexible probes of the detector will show the direction to the fault on the easy understandable display. The step voltage potential will increase when the fault is approached. The point of polarity reversal (zero) will indicate the precise location of the fault.
