The HZJS-V Anti-Interference Dielectric Loss Automatic Measuring Instrument adopts frequency-conversion power supply technology and utilizes microcontroller and electronic technology to carry out automatic frequency conversion, analog/digital conversion, and data arithmetic. This achieves strong anti-interference ability, fast testing speed, high precision, and easy operation.
The frequency-conversion power supply uses a high-power switching power supply, outputting single-frequency 45Hz–65Hz and dual-frequency 47.5Hz/52.5Hz, 45.0Hz/55.0Hz, 57.5Hz/62.5Hz, and 55.0Hz/65.0Hz pure sine waves with automatic pressurization. It automatically filters out 50Hz interference, making it suitable for field testing in substations and other environments with electromagnetic interference.
