Description
Overview
GAOTek portable DC system ground-fault locator produced by ultra-high voltage is a new generation of testing equipment. It can be applied to DC systems of any voltage level and is equipped with high-precision detection clamp meters, greatly improving the detection range and anti-interference ability through efficient processing of multiple signals. Advanced algorithms and advanced fuzzy control theory of computation are used to express the superiority of the detected insulation branch in numerical form, which fully reflects the superiority of artificial intelligence. For the determination of the location of the grounding point.
