What Are the Factors Influencing the Impact of Lightning on 10kV Distribution Lines?
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

Analysis of Substation Busbar Discharge Faults and Their Solutions
1. Methods for Detecting Busbar Discharge1.1 Insulation Resistance TestThe insulation resistance test is a simple and commonly used method in electrical insulation testing. It is highly sensitive to through-type insulation defects, overall moisture absorption, and surface contamination—conditions that typically result in significantly reduced resistance values. However, it is less effective in detecting localized aging or partial discharge faults.Depending on the equipment’s insulation class and
