Surge generators are mainly used for the location of faults in power cable networks. They come in a variety of models from low voltage to very high voltages.
The instrument described on this page generates voltages selectable between 3 or 32 kV and is typically used in the location of faults in low voltage networks such as street lighting or smaller consumers.
The maximum storage energy of the capacitor is 2000J at 8, 16 and 32kV.
All Surge generators generate high voltages from the mains supply voltage, which is rectified and used to charge capacitors, which is in turn discharged into a faulty cable at adjustable intervals.
The unit has an internal automatic dump contractor which, upon power failure or turn off, 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 up to the selected output levels. Our very successful Arc-Echo method is added to this unit and forms part of the framework.
