[0002] Electrical tests are carried out before the electrical system and electrical equipment are put into use to determine whether there are quality problems in installation or manufacturing, so as to determine whether the newly installed or operating electrical equipment can be normally put into operation. For the insulation performance, electrical characteristics, mechanical properties, etc. of each electrical equipment monomer in the electrical system, tests and verifications are carried out item by item according to the relevant regulations in the standards, codes and specifications. Through these tests and verifications, defects, errors and quality problems in the manufacture and installation of electrical equipment can be discovered and eliminated in time, ensuring that the electrical system and electrical equipment can be normally put into operation.
