Abstract

The distribution transformers are easily damaged when struck by lightning, the reliability of power supply and distribution system as well as the operational safety will be affected seriously. Therefore, it is necessary to find out a relatively thorough lightning protection measure, to ensure the safe and stable opreation of distribution transformer. This paper puts forward a new protection method which combines surge arresters with power cables. And then, Electro-Magnetic Transient Program (EMTP) is used to verify the effectiveness of the method. The results shows that the method is simple and easy to implement, without additional electrical equipment, provides a new effective theoretical way for lightning protection of distribution transformers.
