On December 1, 2017, the National Energy Administration made corresponding adjustments to the equipment for electric power commissioning and testing qualifications. The equipment for commissioning and testing qualifications in each province is the same, while some equipment that is not commonly used in the actual work of electric power enterprises has been omitted. Obtaining the Level 4 commissioning and testing qualification allows for installation, repair, or testing activities of electric power facilities with voltage levels below 35 kV.
Level 4 commissioning and testing equipment includes series resonance, power frequency withstand voltage test devices, DC high voltage generators, induced withstand voltage test devices, dielectric loss testers, loop resistance testers, and transformer ratio testers.
Article 17: Those who obtain the Level 4 commissioning and testing (installation, repair, and testing) license for electric power facilities can engage in testing activities for electric power facilities with voltage levels below 35 kV. Applicants shall meet the following conditions:
(1) Legal person qualification and a sound organizational structure;
