The core working principle of the insulation oil withstand voltage tester is to simulate the electric field environment during the actual operation of power equipment. By applying a steadily increasing AC high voltage to the insulation oil sample until it undergoes breakdown discharge, the insulatio

1. Precautions for Preparation Before TestingIt is necessary to confirm the reliable grounding of the equipment, and the grounding resistance must meet the requirements (usually ≤ 4 Ω) to avoid the risk of electric shock during high-voltage testing.Check the appearance of the equipment, test the c

Insulation performance testThe core function of a lightning impulse generator is to conduct insulation impulse withstand voltage tests on high-voltage electrical equipment such as transformers, cables, insulators, etc. It assesses the insulation strength of these specimens under overvoltage by gener

1、 Preparation before testing: laying the foundation for precise testingThe core of the preparation phase is to clarify cable information, ensure equipment reliability, and clean up the on-site environment to avoid testing deviations or safety hazards caused by previous omissionsCollect basic infor
