The HZJS-III Anti-interference Different Frequency Dielectric Loss Tester adopts frequency conversion power supply technology, utilizing micro-controllers and electronic technology for automatic frequency conversion, analog-to-digital conversion, and data computation. This results in strong anti-interference capability, fast testing speed, high accuracy, and easy operation.
The frequency conversion power supply uses a high-power switching power supply, outputting single frequency 45Hz–65Hz and dual frequencies 47.5Hz/52.5Hz, 45.0Hz/55.0Hz, 57.5Hz/62.5Hz, and 55.0Hz/65.0Hz pure sine waves, with automatic voltage regulation. It automatically filters out 50Hz interference, making it suitable for on-site testing in substations with high electromagnetic interference.
