Megger ARM 3 E lets you relocate high resistance faults by providing rapid-term stabilization of an arc. The arc is later ignited by a surge greeting generator (SWG) where surge voltages of taking place to 32 kV are allowed.

The ARM 3-E eliminates tall impedance in the current circuit, allowing the SWGs ignition to be used to full effect. This makes it ideal for finding faults in long cables, that once poor transmission or those in unconditionally wet conditions.
