SURGE GENERATORS : SG7505

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 networks.

The maximum storage energy of the capacitor is 270 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 set 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.

Ask an Adret consultant if you are not sure whether a 5kV surge generator will meet your needs.
