The small current grounding line selection has been a problem that has plagued the power system for long. Since 1991, our company has developed and produced small current grounding line selection products together with Institute of Electronic and Information Engineering, UESTC and North China Electric Power University. The rate of the line selection is improved combining the transient analysis principle, wavelet technology, the fundamental wave line selection method, the quintuple harmonics method, the active power method and other methods. According to the test results and the actual operation, the **** rate of the line selection for the MLD-KY series small current grounding line selection device is above 98%. Especially in solving the inaccurate line selection problem of the arc suppression coil system, our company has performed well and won the respect and recognition of customers. The market share of this product is approximately 40%, reaching the leading level in China. It has been widely used in 3~66kV systems in the power, chemical, petroleum, metallurgy, coal, mining, petrochemical and other industries.
