Product Overview
    Dielectric loss measurement is a very basic method in insulation testing, which can effectively detect overall moisture, deterioration, and local defects in electrical equipment insulation. It is widely used in electrical manufacturing, electrical equipment installation, handover, and preventive tests.
The measurement of dielectric loss in transformers, transformers, reactors, capacitors, bushings, and arresters is a basic method to evaluate their insulation performance.
The automatic anti-interference precision dielectric loss tester breaks through the traditional bridge measurement method, adopts variable frequency power supply technology, uses single-chip microcomputer and modern electronic technology for automatic frequency conversion, A/D conversion, and data calculation; it has strong anti-interference ability, fast test speed, high accuracy,
fully automatic digitalization, and simple operation; the power supply uses a high-power switching power supply with automatic voltage boosting; it automatically filters out 50Hz interference, suitable for on-site testing in environments with strong electromagnetic interference such as substations. It is widely used for dielectric loss measurement of transformers, transformers, bushings, capacitors, arresters, and other equipment in the power industry.
