Product Details

MEJD-40A Grounding Downlead Conductivity Tester

The reliable and effective connection between the grounding and grounding of power equipment is the fundamental guarantee for the safe operation of the equipment.groundingConductivity is the connection between power equipment and the ground grid. During the long-term operation of power equipment, the connection may be affected by moisture and other factors, resulting in node corrosion, even fracture, and other phenomenaGrounding down conductorThe resistance at the connection point with the main grounding grid increases, making it unable to meet the requirements of power regulations, resulting in potential safety hazards during equipment operation, and in severe cases, causing the equipment to lose ground and operate.MEJD-40A Grounding Downlead Conductivity TesterIt is a highly automated portable testing instrument developed by our company, used for measuring the conductivity resistance between grounding down conductors of various power equipment in substations.
