Product Introduction
Dielectric loss insulation testing can effectively detect overall moisture, deterioration, and aging of electrical equipment insulation, as well as local defects, and is widely used in electrical manufacturing, electrical equipment installation, commissioning, and preventive testing.
This instrument adopts variable frequency power supply technology, utilizing microcontroller and electronic technology for automatic frequency conversion, A/D conversion, and data calculation, achieving strong anti-interference capability, fast testing speed, high accuracy, and easy operation.
The variable frequency power supply uses a high-power switching power supply, outputting pure sine waves at 45Hz and 55Hz, with automatic voltage boosting, providing up to 10kV voltage; it automatically filters out 50Hz interference, making it suitable for on-site testing in environments with high electromagnetic interference such as substations.
