In order to implement a 100 % stator earth fault protection based on sub harmonic injection, a 20Hz voltage is injected into the generator star point. The 20-Hz generator SGEN-1001 is used in combination with the band pass filter SBPF-1001 in the Stator Earth fault protection. Injection can be performed by connecting the SGEN-1001 and the SBPF-1001 to the load resistor of an earthing or neutral transformer. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. From the driving voltage and the fault current, the protective relay determines the fault resistance.

Underground cable fault locator, 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.

detection of cables in ceilings, walls and floors,detection of breaks in cables,tracing cables in building installation, locating power points and switches in buildings,locating short circuits between leads,Non-contact detection of live cables, the function 3D in the receiver – detecting the direction of current flow and accurate locating the object.

The FLS-240 Pocket Pal Visual Fault Locator is a straightforward solution for identifying breaks, bends, faulty connectors or splices, as well as other causes of signal loss. It can detect faults over distances of up to 5 km. The FLS-240 visually locates faults by creating a bright red glow at the exact location of the fault on singlemode or multimode fibers.
