Overview

The grounding wire group DC resistance tester is developed according to the requirements of the "Preventive Test Regulations for Power Safety Tools" and is used for group DC resistance testing. The grouped DC resistance test is used to assess whether the contact between the nose of the portable short-circuit grounding wire and the busbar clamp and the multi stranded copper flexible wire is good. At the same time, it is also possible to assess whether the cross-sectional area of multi job steel flexible conductors meets the requirements. One machine is versatile and can also be used for ground conduction and contact resistance testing!

1Grounding wire group DC resistance testerOverview

In the power system, portable short-circuit grounding wires and personal protective grounding wires play a crucial role in preventing sudden incoming electricity to electrical equipment and lines, eliminating induced voltage, and discharging residual charges. In order to prevent unqualified grounding wires from entering the power system, our company has developed a "grounding wire group tester" in accordance with the "Technical Standards for Portable Short Circuit Grounding Wires" and the latest "Preventive Experimental Regulations for Power Safety Tools" issued and implemented by the State Power Corporation, providing services for the completion of necessary product preventive experiments in the power system.

IIGrounding wire group DC resistance testerFeatures

The whole machine is controlled by a high-speed microcontroller, with a high degree of automation and easy operation.

2. The instrument adopts a new power technology, with stable output current, high output voltage, fast measurement speed, wide range, suitable for testing various portable short-circuit grounding wires and personal protective grounding wires.
