Insulating Oil Dielectric Loss and Resistivity Analyzer Lab Oil Dielectric Loss Resistivity Test Equipment
Product Introduction:
This instrument is a new generation fully automatic portable insulating oil dielectric loss and resistivity tester designed according to the national standard GB/5654. It can simultaneously measure oil dielectric loss and volume resistivity, and features simple operation and accurate and reliable test data.
Main Features:
1. Adopts an LCD screen; the instrument automatically performs tests and automatically stores and prints test results according to the Chinese menu prompts.
2. The oil cup adopts a three-electrode structure conforming to the national standard GB/T5654-2007, with an inter-electrode distance of 2mm, which eliminates the influence of stray capacitance and leakage on the dielectric loss test results.
3. The instrument uses medium-frequency induction heating and PID temperature control algorithm, offering advantages such as non-contact between the oil cup and the heating element, uniform heating, fast speed, and convenient control, ensuring that the temperature is strictly controlled within the preset temperature error range.
4. The internal standard capacitor is an SF6 gas-filled three-electrode capacitor. The dielectric loss and capacitance of this capacitor are not affected by ambient temperature, humidity, etc., ensuring the accuracy of the instrument even after long-term use.
5. 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. The instrument can operate correctly even when powered by a generator.
6. Comprehensive protection functions. In case of overvoltage, overcurrent, or high-voltage short circuit, the instrument can quickly cut off the high voltage and issue a warning message. A warning message is issued if the temperature sensor fails or is not connected. A temperature limiting relay is installed in the medium-frequency induction heating furnace; when the temperature exceeds 120°C, the relay releases, and heating stops.
7. Convenient test parameter settings. Temperature setting range: 0~125ºC, AC voltage setting range: 500~2200V, DC voltage setting range: 0~500V.
8. Empty electrode cup calibration function: measures the capacitance and dielectric loss factor of the empty electrode cup to determine the cleaning and assembly condition of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.
