On December 1, 2017, the National Energy Administration made corresponding adjustments to the equipment for electric power testing qualification. The testing qualification equipment in each province is the same, and some equipment that is not commonly used in the actual work of electric power enterprises has been omitted. Obtaining the fourth-level testing qualification allows for the installation, repair, or testing of electric power facilities with voltage levels below 35 kV.
The fourth-level testing equipment includes series resonance, power frequency withstand voltage test devices, DC high voltage generators, induced voltage withstand test devices, dielectric loss testers, loop resistance testers, and transformer ratio testers.
Article 17: Those who obtain the fourth-level testing qualification for installation (repair, testing) of electric power facilities can engage in testing activities for electric power facilities with voltage levels below 35 kV. Applicants shall meet the following conditions:
