Active ARM fault location with built-in impulse generation
Conduct prelocation with either the surge generator or directly for LV fault location
Compatible with all surge generators and re ectometers
The ARM 3-E lets you prelocate high resistance faults by providing short-term stabilisation of an arc. The arc is then ignited by a surge wave generator (SWG) where surge voltages of up to 32 kV are allowed.
The ARM 3-E also eliminates high impedance in the current circuit, allowing the SWG’s ignition to be used to full effect. This makes it ideal for finding faults in long cables, those with poor transmission or those in extremely wet conditions.
