5kV 750 Joule Surge Generator

The SG7505 surge generator generates voltages between 3 or 5 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 500 J at 3KV and 750 J at 5KV. 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 up to the selected output levels.
