Wuhan UHV Power Technology Co.,Ltd.

Wuhan UHV Power Technology Co.,Ltd. The Variable Frequency Line Parameter Tester is a high-precision instrument for on-site testing of power frequency parameters of various high-voltage transmission lines (overhead, cable, and mixed overhead and cable). The instrument features an integrated structure with a built-in variable frequency power supply module, enabling variable frequency and voltage output. The frequency can be adjusted to 47.5Hz/52.5Hz, 45.0Hz/55.0Hz, 57.5Hz/62.5Hz, and 55.0Hz/65.0Hz, respectively. It utilizes digital filtering technology to eliminate interference from power frequency...

Wuhan UHV Power Technology Co.,Ltd. 3. All measurement processes require only a 220V mains connection, eliminating the inconvenience of 380V on-site connection required by existing measurement methods. 4. A unique internal anti-inductive voltage circuit ensures the instrument can withstand higher inductive voltages (up to 30A), allowing it to operate normally even at high inductive voltages of 10,000V. 5. Strong anti-interference capability: The instrument's built-in variable-frequency power supply module provides output power, with adjustable frequencies of 47.5Hz/52.5Hz, 45.0Hz/55.0Hz, 57.5Hz/62.5Hz,...
