The low voltage cable fault location system STG 600 includes a surge generator, a high voltage source for testing and precise location of sheath and cable insulation faults. The STG 600 is a multifunctional cable fault locating set especially designed for low voltage power distribution networks.

The surge and test generator is used for cable testing and for pin-pointing of high-resistance and intermittent faults in low voltage cables. An optional coupling filter can be integrated in the STG 600 enabling the use of the highly sophisticated and efficient prelocating method: secondary impulse method/multiple impulse method (SIM-MIM).
