DC system grounding fault tester produced by Wuhan UHV is a new generation of tester. It can be applied to dc systems of any voltage grade. It is equipped with high-precision detection clamp table, which greatly improves the detection range and anti-interference ability through efficient processing of multiple signals. Advanced algorithm and fuzzy control theory are adopted to express the superiority degree of detected insulation branch in numerical form, which fully reflects the superiority of artificial intelligence. They have accurate judgment on the location of the grounding point, and can point out the location and direction of the grounding point every time.

DC system grounding fault tester takes system safety as the primary premise, conducts detection in a reliable low-frequency signal in strict accordance with the requirements of industry standards, and carries out a large number of practical applications in the field, without any impact on the system.

Dc systems in power plants and substations provide power supply for control, protection, signals and automatic devices. The safe and continuous operation of dc systems is of great importance to ensure power supply and distribution. As the dc system is not grounded by floating system, if two-point grounding occurs, it may cause the above devices to misoperate and refuse to operate, thus causing a major accident. Therefore, when one point grounding occurs, the grounding point should be accurately and quickly detected while ensuring the normal power supply of the dc system to eliminate the grounding fault, so as to avoid the possible harm of two points grounding.

DC system grounding fault tester is used to find the exact location of DC system grounding points of power plants and substations in the case of constant electricity. All kinds of grounding faults can be found out quickly with good accuracy.
