• High-voltage transmission cables, distribution equipment, generators, transformers, and high-voltage circuit breakers are core components in power plants and substations. The insulation integrity of such equipment must be verified through specialized testing and inspection.
• In industrial production, the full lifecycle management of electrical equipment-including motors, variable frequency drives, and machine tools-encompasses critical phases such as factory acceptance testing, regular maintenance, and troubleshooting.
• During the completion phase of construction projects, acceptance testing of the insulation performance of electrical circuits, distribution panels, and lighting/power systems is an indispensable step.
• In laboratory environments, electrical testing primarily involves the precise calibration of critical parameters such as leakage current and insulation resistance for electronic components and insulating materials.
• Beyond mainstream applications, this testing methodology can also be applied to assess the insulation status of electrical equipment in chemical and railway industries. It is particularly well-suited for testing capacitive specimens and conducting tests in high-interference scenarios.
