  • Product Introduction

       The safety characteristics of DC protection devices are generally tested in national laboratories or test stations. The equipment covers a large area and requires special charging devices and high current load boxes. The operation is complicated and the current-action time characteristics cannot be accurately tested. . Therefore, after the DC system is put into operation, the on-site maintenance personnel cannot verify whether the safety characteristics of the DC protection device meet the requirements because they do not have the corresponding testing means and tools.
      According to the reality of the DC protection characteristics of DC protection appliances, the company has introduced a verification of the operating characteristics and differentials of DC protection appliances in order to improve the reliability of DC system operation and ensure the safe and reliable operation of the grid.
