Designed to fit in a small suitcase sized "Pelican" enclosure and produce 52 or 58 Hz at up to 10A rms 250V peak.

Our client uses this equipment for verification of earth mat integrity around power stations and switch yards

It is much more portable than a 5kVA generator and is locked on frequency and gives a constant ground current between the electrodes.

Highly tuned 58/52 Hz filtered voltmeters are used to measure the volt drops in the ground.
