T-S12 High Voltage Surge Generator

The T-S12 high voltage surge generator, is used for locating high impedance and flashing faults on low voltage distribution cables. It works in conjunction with a cable fault locator (e.g. Kehui T-906) for pre-locating the fault position and then with a pinpointer (e.g. Kehui T-506) to find the precise fault location. It is applicable for different cable fault location techniques, such as the impulse current method (ICM) and the secondary/multiple impulse method (SIM/MIM).
