Analysis of Lightning Protection Measures for Distribution TransformersTo prevent lightning surge intrusion and ensure the safe operation of distribution transformers, this paper presents applicable lightning protection measures that can effectively enhance their lightning withstand capability.1. Lightning Protection Measures for Distribution Transformers1.1 Install surge arresters on the high-voltage (HV) side of the distribution transformer.According to SDJ7–79 Technical Code for Overvol

What lightning protection measures are used for H61 distribution transformers?A surge arrester should be installed on the high-voltage side of the H61 distribution transformer. According to SDJ7–79 "Technical Code for Design of Overvoltage Protection of Electric Power Equipment," the high-voltage side of an H61 distribution transformer should generally be protected by a surge arrester. The grounding conductor of the arrester, the neutral point on the low-voltage side of the transformer, and the

1. Induced Lightning OvervoltageInduced lightning overvoltage refers to the transient overvoltage generated on overhead distribution lines due to nearby lightning discharges, even when the line is not directly struck. When a lightning flash occurs in the vicinity, it induces a large amount of charge on the conductors—opposite in polarity to the charge in the thundercloud.Statistical data shows that lightning-related faults caused by induced overvoltages account for approximately 90% of total fau

With the rapid development of China's economy, the power industry has also gradually expanded in scale, increasing the requirements for both the installed capacity and the single-unit capacity of power transformers. This article provides a brief introduction to four aspects: transformer construction, transformer lightning protection, transformer faults, and transformer noise.A transformer is a commonly used electrical device capable of converting AC electrical energy. It can transform one form o
