In the field of electrical engineering and maintenance, ensuring the reliability and efficiency of insulating oil is extremely important. The Insulating Oil Dielectric Loss and Resistivity Tester is an indispensable tool for professionals dedicated to maintaining the integrity of electrical systems. This advanced device is designed to measure the dielectric loss (tan delta) of insulating oil, 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 "Measurement of Relative Permittivity, Dielectric Loss Factor, and DC Resistivity of Liquid Insulating Materials". It is used for measuring the dielectric loss factor and DC resistivity of insulating oil and other insulating liquids. This device features an integrated structure, combining a test cell, temperature controller, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, high resistance meter, and DC high voltage source as its main components. It adopts fully digital technology and fully automatic measurement, equipped with a large (800*480) LCD display. The device supports Chinese at each step, and test results can be automatically saved and printed, making it easy to use even for operators without specialized training.Main FeaturesComplies with national standard GB/T5654-2007, using a three-electrode structure test cell (2mm electrode gap) to eliminate the influence of stray capacitance and leakage current on measurement results. The device is equipped with an oil discharge solenoid switch, allowing for cleaning with test samples without removing the test cell if not necessary.Adopts medium-frequency induction heating and PID temperature control algorithm. This heating method ensures non-contact between the test cell and the heating body, minimal heat loss, fast heating speed, easy control, and precise temperature control within the set error range.The internal standard capacitor is a three-electrode capacitor filled with SF6 gas, ensuring that the dielectric loss and capacitance of the standard capacitor are not affected by ambient temperature and humidity, maintaining measurement accuracy over long-term use.The AC test power supply uses AC-DC-AC conversion, avoiding the influence of main power voltage and frequency fluctuations on measurement accuracy. The device can operate normally even with a generator.Comprehensive protection functions: In case of overvoltage, overcurrent, or high voltage short circuit, the instrument quickly cuts off the voltage and issues an alarm message. If the temperature sensor malfunctions or is not connected, the instrument also issues an alarm message.The medium-frequency induction heating furnace has a built-in temperature limit relay, which disconnects and stops heating if the temperature exceeds 120°C.Improved parameter settings for easier operation. Temperature setting range: 0~125°C, AC voltage setting range: 500~2000V, DC voltage setting range: 0~500V.Large LCD display with backlight for clear display. User-friendly interface allows for command input via the Chinese menu prompt, and the device automatically performs the test. Test results are automatically saved and printed.Built-in real-time clock, saving the date and time of tests, and displaying and printing test results accordingly.Calibration function for dried cells after cleaning. By measuring the capacitance and dielectric loss factor of the dried cell, the device can determine the cleaning and assembly conditions. Calibration data is automatically saved, making calculation of relative permittivity and DC resistivity easier.Main Technical SpecificationsPower Supply: AC 220V ±10%Power Frequency: 50Hz/60Hz ±1%Measurement Range:Capacitance: 5pF~200pFRelative Permittivity: 1.000~30.000Dielectric Loss Factor: 0.00001~100DC Resistivity: 2.5MΩm~20TΩmMeasurement Accuracy:Capacitance: ±(1% of reading + 0.5pF)Relative Permittivity: ±1% of readingDielectric Loss: ±(1% of reading + 0.0001)DC Resistivity: ±10% of readingResolution:Capacitance: 0.01pFRelative Permittivity: 0.001Dielectric Loss: 0.00001Temperature Measurement Range: 0~125°CTemperature Measurement Error: ±0.5°CTest Voltage AC (RMS): 500~2000V, continuously adjustable, 50HzTest Voltage DC: 0~500V, continuously adjustablePower Consumption: 100WDimensions: 500×360×420 mmWeight: 22kgOperating ConditionsAmbient Temperature: 0°C~40°CRelative Humidity (RH): (see images for details)Features / Technical SpecificationsModel: HZJD-2ZBrand: HuazhengPower Supply: AC 220V ±10%Frequency: 50Hz/60Hz ±1%Capacitance Range: 5pF~200pFRelative Permittivity Range: 1.000~30.000Dielectric Loss Factor Range: 0.00001~100DC Resistivity Range: 2.5MΩm~20TΩmMeasurement Accuracy: Capacitance ±(1% of reading + 0.5pF), Relative Permittivity ±1% of reading, Dielectric Loss ±(1% of reading + 0.0001), DC Resistivity ±10% of readingResolution: Capacitance 0.01pF, Relative Permittivity 0.001, Dielectric Loss 0.00001Temperature Measurement Range: 0~125°CTemperature Measurement Error: ±0.5°CTest Voltage AC (RMS): 500~2000V, continuously adjustable, 50HzTest Voltage DC: 0~500V, continuously adjustablePower Consumption: 100WDimensions: 500×360×420 mmWeight: 22kg
