SG80034

34KV 1450 Joule Mining Cable Shop Surge Generator

The SG80034 surge generator generates voltages adjustable from 0 to 34kV and is typically used in the location of faults in mining cable shops. The maximum storage energy of the capacitor is 1450Joules at 7.5, 17 or 34kV. All surge generators generate high voltages from the mains supply voltage, which is rectified and used to charge capacitors, which are in turn discharged into a faulty cable at adjustable intervals. The unit has an internal automatic dump contactor which discharges both the unit and the cable under test. This is activated when the unit is turned off or when a power failure occurs. It can be operated in the single shot or continuous pulsing method if correct selection is made.

The unit can also be used to perform insulation resistance tests in the 34kV selected output level.
