MRD-196H grounding device of the small current


Model: MRD
MRD-196H series fault wire location device of low current adpots 80C 196 single-chip mirocomputer for analyzing, applicable to 0.38KV~66KV power system of unground or ground via arc-suppression coil as well as via neutral ground resistor. No matter metal grounding, gap grounding, arc flash grounding or accompanied ferromagnetic resonance grounding, it could accurately locate the grounding wire without limit to wire-out way (over-head line or underground cable line)
As following of the feature:
Do not need setting, debugging is simple, and small amount of the maintenance
Application range, unlimited length line, and series-parallel operation qualification of any number
Can distinguish the grounding and bus grounded
Analysis speed, is testing lines appear ground fault, can be 1 seconds the analysis
Automatic storage formed 12 the faulty information
When one-phase ground fault happens measurement circuits, alarm signal output device, trip output contacts are closed
