In recent years, in response to global warming and climate change caused by greenhouse gas emissions, many countries have focused on promoting electric vehicles to replace traditional fuel vehicles. And the construction of charging piles is very important in the promotion of new energy vehicles. Therefore, a large number of charging pile projects have emerged around the world.
The company is a charging pile manufacturer located in South Korea, using our DC energy meter DJSF1352-RN to match their DC charging pile. After using it for a period of time, they’re very satisfied with the quality of our products.
3.1 Physical electric shock
When shell of the electrical equipment is electrified due to insulation damage and the workers touch the shell again, it will lead to physical electric shock accident.
3.2 Burn electrical equipment and cause fire
The long-term leakage current, especially the leakage current of two-phase grounded through resistance, will release a lot of heat when flow through the damaged part of the equipment insulation, further damaging the insulation, and even making combustible materials (such as non flame retardant rubber sheathed cable) burn on fire.
3.3 Cause short circuit accident
According to statistics, about 30% of single-phase grounded faults develop into short circuit which will give rise to heavier electrical failure. The long-term leakage current and spark further damage the insulation at the leakage point, and finally endanger the interphase insulation and cause short circuit.
3.4 Cause electrical fire accident
When the single-phase grounding occurs in the power grid or the single-phase collision occurs in the equipment, the electric spark will be generated at the grounding point. If the electric spark has enough energy, it may ignite flammable and explosive materials.
