With the rapid development of China power industry, electrical preventive experiment is an important aspect of electrical power system safe operation and maintenance work. Insulation diagnosis is an important tool to detect the in sulation or fault of electrical equipment
Currently, electrical equipment (such as transformers, generators, etc.) toward the trend of large capacity, high voltage, structural diversification and sealing, this requires insulation resistance tester with advantages of large capacity, strong anti-interference ability, easy to carry and so on. So we designed and developed the series meter especially for strong interference field test for large high voltage transformers, electrical appliances, remote power cables or laying cables and other electrical insulation resistance properties for high-voltage substations, power plants and others.
The instrument system combines analog circuits, digital circuits, mechanically operated advantages, achieved a leading position at the output voltage, output current, measuring range, measurement accuracy, anti-interference ability.
