Insulating Oil Dielectric Loss and Resistivity Tester

Insulating Oil Dielectric Loss And Resistivity Tester

Developed in compliance with the national standard GB/T5654-2007, the ME-W8500 Insulating Oil Dielectric Loss and Volume Resistivity Tester uses medium-frequency induction heating and a three-electrode automated oil-drain cup. It is easy to operate and has a large-screen color touch display. It includes extensive safety safeguards along with completely automatic temperature ramping, temperature control, data storing, and printing features. It provides accurate and trustworthy findings and is appropriate for preventive testing of insulating oil properties in power equipment.

1. Utilizing advanced measurement principles and highly digitalized technology, it fully automates processes including heating, temperature control, high-speed data sampling, computation, display, printing, and storage;

2. The oil cup adopts a three-electrode structure compliant with national standard GB/T5654-2007, featuring a 2mm inter-electrode spacing to eliminate the impact of stray capacitance and leakage current on dielectric loss test results;

3. The instrument employs medium-frequency induction heating. This heating method offers advantages such as non-contact heating between the oil cup and heating element, uniform heating, rapid heating speed, and convenient control, ensuring the temperature is strictly maintained within the preset temperature tolerance range.

4. It incorporates a standard capacitor. The dielectric loss and capacitance of this capacitor are unaffected by environmental factors such as temperature and humidity, ensuring the instrument's accuracy remains guaranteed even after prolonged use.

5. Large color touchscreen facilitates user interaction with intuitive, straightforward operation.

6. Safety alerts for high-voltage disconnection upon lid opening and short-circuit between oil cup electrodes eliminate hazards, safeguarding personnel and equipment.

7. Built-in real-time clock saves, displays, and prints test dates/times alongside results.

8. Automatically stores up to 100 sets of measurement data with fast thermal printing.

9. Features empty electrode cup calibration capability.

10. Calibration data is automatically saved for precise calculation of relative permittivity and DC resistivity.

11. Features an automatic oil-drain cup design, enabling oil replenishment or cleaning without removing the cup. Oil samples are automatically drained after testing.

This instrument is suitable for preventive insulation testing of electrical equipment, measuring parameters such as dielectric loss factor, volume resistivity, and relative permittivity of insulating oil. It complies with the national standard GB/T5654-2007 and meets the power industry's demand for precise and convenient measurement of insulating oil parameters.
