Supply of 10A grounding downlead continuity tester

The power industry standard DL/T475-2006 "Guidelines for Measuring Characteristic Parameters of Grounding Devices" stipulates that electrical conductivity should be measured using specialized instruments with a resolution of 1m Ω and an accuracy of not less than 1.0 level. It is a highly automated portable tester specifically designed for electrical integrity testing of grounding devices, with all technical indicators meeting or exceeding relevant standard requirements. The instrument is easy to operate, has high accuracy, fast testing speed, good repeatability, and intuitive readings. It is an ideal instrument that meets the requirements of regulations, greatly facilitating the development of experimental projects and improving work efficiency.

Product Overview:

The electrical connectivity between the various parts of the grounding device and the equipment, namely the DC resistance value, also known as electrical conductivity. The reliable and effective connection between the grounding down conductor of power equipment and the grounding grid is the fundamental guarantee for the safe operation of the equipment. The grounding down conductor is the connecting part between power equipment and the grounding grid. During the long-term operation of power equipment, the connection may be affected by factors such as moisture, resulting in node corrosion or even breakage, which increases the resistance of the connection point between the grounding down conductor and the main grounding grid and cannot meet the requirements of power regulations. This poses a safety hazard to the equipment during operation, and in severe cases, it may cause the equipment to lose ground and operate. The underground grounding electrode and its connecting parts of the grounding device may also experience rusting or even breakage. Therefore, it is necessary to conduct regular electrical integrity tests on grounding devices.
