In the realm of electrical engineering and maintenance, ensuring the reliability and efficiency of insulating oils is paramount. The Insulating Oil Dielectric Loss Tan Delta Tester emerges as an indispensable tool for professionals dedicated to maintaining the integrity of electrical systems. This sophisticated device is designed to measure the dielectric loss, or tan delta, of insulating oils, providing critical insights into the condition and performance of these essential materials.OverviewHZJD-2Z Insulating oil dielectric loss and resistivity tester is designed and manufactured based on GB/T5654-2007 of “Liquid insulating material of relative permittivity, dielectric loss factor and DC resistivity measurements”. It is used for measuring dielectric dissipation factor and DC resistivity of insulating oil and other insulating liquids. The instrument is characterized by integrated structure, and integrates test cell, temperature controller, temperature sensor, dielectric loss test bridge, AC test power, standard capacitor, high resistance meter, DC high voltage source and other major components. The instrument adopts full digital technology and all of the intelligent automatic measurement, is equipped with large color screen (800*480) LCD display, which each step has prompted the Chinese, the test results can be automatically stored and printed output, so that the operator without professional training will be able to use it proficiently.The Main Functions And FeaturesThe test cell uses a three-electrode structure in line with the national standard GB/T5654-2007, with electrode spacing 2mm, eliminating the effects of stray capacitance and leakage on dielectric loss test results. Equipped with an oil drainage solenoid switch, the test cell can be emptied and rinsed with the test sample without removal.The instrument adopts medium frequency induction heating and PID temperature control algorithm. This heating method ensures non-contact between the test cell and the heating body, even heating, fast speed, convenient control, and strict temperature control within the preset error range.Internal standard capacitor is SF6 gas-filled three-electrode capacitance, with dielectric loss and electrical capacity independent of ambient temperature, humidity, and other effects, ensuring accuracy even after prolonged use.AC test power supply uses AC-DC-AC conversion, effectively avoiding fluctuations in mains voltage and frequency affecting dielectric loss measurement accuracy. The instrument can work properly even with a generator.Perfect protection function: In case of over voltage, over current, or high-voltage short circuit, the instrument quickly cuts off pressure and issues a warning message. If the temperature sensor fails or is not connected, the instrument also issues a warning.Temperature limiting relay in the medium frequency induction heating furnace: When temperature exceeds 120°C, the instrument releases the relay and stops heating.Convenient experimental parameter setting: Temperature setting range 0–125°C, AC voltage setting range 500–2000V, DC voltage setting range 0–500V.Large-screen LCD display with backlight and clear display. Friendly interface, follow the Chinese menu prompt, enter the command, and the instrument can be automatically tested. Test results can be automatically stored and printed.Built-in real-time clock: Test date and time may be saved, displayed, and printed with the test results.Calibration functions for cleaned dry cell: Measurement of dry cell’s capacitance and dielectric loss factor can determine its cleaning and assembly conditions. Calibration data is automatically saved, facilitating calculation of relative permittivity and DC resistivity.Major Technical IndicatorsVoltage supply: AC 220V±10%Power frequency: 50Hz/60Hz ±1%Measuring range:Electric capacity: 5pF–200pFRelative Permittivity: 1.000–30.000Dielectric loss factor: 0.00001–100DC Resistivity: 2.5MΩm–20TΩmMeasuring accuracy:Electric capacity: ± (1% of measured value + 0.5pF)Relative Permittivity: ±1% of measured valueDielectric dissipation factor: ± (1% of measured value + 0.0001)DC Resistivity: ±10% of measured valueResolution:Electric capacity: 0.01pFRelative capacitivity: 0.001Dielectric dissipation factor: 0.00001Measured temperature range: 0–125°CTemperature measurement error: ±0.5°CTest Voltage AC (RMS): 500–2000V Continuously adjustable, frequency 50HzTest Voltage DC: 0–500V Continuously adjustablePower consumption: 100WExternal dimensions: 500×360×420 mmTotal weight: 22KgUse ConditionAmbient temperature: 0°C–40°CRelative humidity (RH): <75%Technical Specifications / FeaturesModel: HZJD-2ZIntegrated structure with test cell, temperature controller, temperature sensor, dielectric loss test bridge, AC test power, standard capacitor, high resistance meter, DC high voltage sourceFull digital technology, intelligent automatic measurementLarge color LCD display (800*480)Automatic storage and printout of test resultsMedium frequency induction heating, PID temperature controlSF6 gas-filled standard capacitorAC-DC-AC conversion for test power supplyOvervoltage, overcurrent, and high-voltage short circuit protectionTemperature limiting relay for safetyCalibration function for dry cell
