Description
Features:
• Used for measuring the dielectric loss factor and DC resistivity of liquid insulating media such as insulating oil;
• The oil cup electrode spacing is 2mm, which eliminates the influence of stray capacitance and leakage on the dielectric loss test results;
• The instrument uses medium-frequency induction heating and PID temperature control algorithm;
• The internal standard capacitor is an SF6 gas-filled three-terminal capacitor;
• The AC test power supply adopts an AC-DC-AC conversion method, effectively avoiding the influence of mains voltage and frequency fluctuations on the accuracy of dielectric loss testing;
• Convenient test parameter settings. Temperature setting range: 0-120ºC, AC voltage setting range: 200-2200V, DC voltage setting range: 0-500V;
• Uses a large-screen TFT full-color LCD touch display for clear display.
