Surge arrester installed

Should close to the distribution transformer side. The metal oxide surge arrester (MOA) is connected in parallel with the distribution transformer during normal operation, with the upper terminal connected to the ground and the lower terminal grounded. When an over-voltage occurs in the line, the distribution at this time will withstand the three-part voltage drop generated by the over voltage through the arrester, lead and grounding device, called residual voltage. In these three parts of the over-voltage, the residual voltage on the arrester is related to its own performance, and the residual voltage value is constant. The residual voltage on the grounding device can be eliminated by connecting the grounding down conductor to the transformer housing and then connecting it to the grounding device. How to reduce the residual voltage on the lead becomes the key to the protection of the distribution.
