In the photovoltaic power station system, the grounding design is a crucial part of the electrical design, which is related to the safety of the power station equipment and personnel. Good grounding design can ensure that the power station is in a safe operating environment for a long time, reduce the frequency of faults, and improve the overall operating efficiency of the power station. Therefore...
The difference between lightning protection grounding and electrical grounding 1. Protective grounding refers to connecting the metal part of the electrical device that is not charged under normal conditions with the grounding device to prevent the part from being charged suddenly under fault conditions and causing harm to the human body. 2. Working grounding is to ground the neutral point of the ...
Reasons for low insulation resistance: When the solar panels or DC cables and joints are damaged or the insulation layer is aging, the problem of low insulation resistance is easy to occur. When the DC cable passes through the bridge, since the edge of the metal bridge may have barbs, the outer insulation of the cable may be damaged during the threading process, resulting in leakage to the ground....
