Product details
Product IntroductionProduct Introduction
With the rapid development of China's power industry, preventive testing of electrical appliances is an important part of ensuring the safe operation and maintenance of the power system. Insulation diagnosis is an important means of detecting insulation or faults in electrical equipment.
At present, electrical equipment (such as transformers, generators, etc.) is developing towards large capacity, high voltage, diversified structure, and sealing. This requires the insulation resistance tester to have the characteristics of large capacity, strong anti-interference ability, and easy portability. For this purpose, our company has specially designed and developed instruments for testing the electrical insulation resistance characteristics of large high-voltage transformers, motors and electrical appliances, remote power cables or buried cables under strong interference sites such as high-voltage substations and power plants.
Our instruments combine the advantages of analog circuits, digital circuits, and mechanical operations, and have achieved a leading position in output voltage, output current, measurement range, measurement accuracy, and anti-interference ability in China.
