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
Mechanical characteristic testingMechanical characteristic testing is the core of circuit breaker testing, focusing on evaluating the time, speed, stroke, and synchronization (synchronicity) of its opening and closing operations and three-phase actions. These parameters directly affect whether the c
1. Power industry: High voltage equipment oil core purification scenarioThe power industry is the most important application area for vacuum oil filters, serving as the insulation oil and lubrication guarantee for various high-voltage electrical equipment.Oil treatment for transformers and reactors:
