Distribution network was the important component of transmission and distribution system for petrochemical enterprise.The lightning over -voltages would make the distribution line trip and then lead to the power supply interruptions , which often caused serious harm to petrochemical production safety , even resulted in serious injury , economic losses and social impacts.In order to ensure the safety and reliability service of distribution network and to reduce stroke-incidence rate of the electric line , integrated measures must be taken to prevent the harm of the lightning over-voltages and improve the reliability of the power supply system.
