Portable DC System Grounding Fault Finder

WXZG-B2 Portable DC System Grounding Fault Finder

Product Overview:

The portable DC system grounding fault locator is a product successfully developed by our company by introducing new phase advance processing and data transfer algorithm technologies from abroad. This instrument enables rapid detection of various grounding and mixed line faults in DC systems, solving the problems caused by various grounding methods such as virtual grounding, high resistance grounding, multi-point grounding, single point grounding, low resistance grounding, direct grounding, mixed line grounding, loop grounding, capacitor grounding, AC grounding, transistor isolation grounding, etc. with poor insulation status. It can quickly locate and locate faults. The instrument can also accurately detect the grounding resistance value, grounding direction, fast fault location, and has functions such as voice intelligence, graphic expression, and direction indication. It is a high-precision detection instrument for DC system grounding fault inspection and positioning.
