MODSYS 22

Surge generators are mainly used for the location of faults in power cable networks. They come in a variety of models from 0-32kV.

The instrument described on this page generates voltages selectable between 0 and 32 kV and is typically used in the location of faults in medium voltage networks where supply availabiliy is critical.

The maximum storage energy of the capacitor is 2200J 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 contactor,  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 voltages.

In combination with our PCA101 or PCA301 TDR Scope, the unit is capable of pre-locating faults before pinpointing.  Depending on which model of TDR is chosen all popular pre-location methods like TDR, Arc-Reflection, Arc-Reflection Multi and Decay is possible.
