The dielectric loss insulation test can effectively detect overall moisture, deterioration, and local defects in the insulation of electrical equipment. It is widely used in electrical manufacturing, electrical equipment installation, handover, and preventive tests.
This instrument adopts variable frequency power supply technology, utilizing microcontrollers and electronic technology for automatic frequency conversion, analog-to-digital conversion, and data processing, achieving strong anti-interference capability, fast test 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, automatically boosting voltage, providing up to 10kV; it automatically filters out 50Hz interference, suitable for on-site testing in environments with high electromagnetic interference such as substations.
