In the field of electrical engineering and maintenance, ensuring the reliability and efficiency of insulating oils is essential. The Insulating Oil Dielectric Loss (Tan Delta) Tester is 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 crucial information about the condition and performance of these essential materials.OverviewThe HZJD-2Z Insulating Oil Dielectric Loss and Resistivity Tester is designed and manufactured based on the GB/T5654-2007 standard for "Liquid insulating materials with relative permittivity, dielectric loss factor, and DC resistivity measurements." It is used to measure the dielectric dissipation factor and DC resistivity of insulating oil and other insulating liquids. The instrument features an integrated structure, combining the test cell, temperature controller, temperature sensor, dielectric loss test bridge, AC test source, standard capacitor, high resistance meter, DC high voltage source, and other main components. It adopts fully digital technology and intelligent automatic measurements, equipped with a large color LCD display (800*480), allowing test results to be stored and printed automatically, enabling operators without professional training to use it efficiently.Main Functions and FeaturesThe test cell, with a three-electrode structure, complies with the national standard GB/T5654-2007, with a 2 mm electrode spacing, eliminating the effects of parasitic capacitance and leakage on dielectric loss test results. The device is equipped with a solenoid oil drain switch, allowing the test cell to be emptied if not removed and rinsed with the test sample.The instrument uses medium-frequency induction heating and PID temperature control algorithm. This heating method offers the advantages of no contact between the test cell and the heating body, uniform heating, high speed, convenient control, and strict temperature control within the preset error range.The internal standard capacitor is a three-electrode capacitance filled with SF6 gas, and its dielectric loss and capacitance are independent of ambient temperature, humidity, and other effects, ensuring the instrument's accuracy even after prolonged use.The AC test power supply uses AC-DC-AC conversion, effectively avoiding fluctuations in grid voltage and frequency that affect dielectric loss measurement accuracy. The instrument can operate correctly even with a generator.Perfect protection function: in case of overvoltage, overcurrent, or high-voltage short circuit, the instrument can quickly cut off the pressure and issue a warning message. In case of temperature sensor failure or disconnection, the instrument will also issue a warning.There is a temperature limiting relay in the medium-frequency induction heating furnace. When the temperature exceeds 120°C, the instrument releases the relay and stops heating.More convenient for setting experimental parameters. Temperature adjustment range: 0 to 125°C, AC voltage adjustment range: 500 to 2000V, DC voltage adjustment range: 0 to 500V.Uses a large LCD screen with backlight and clear display. User-friendly interface: just follow the Chinese menu, enter the command, and the instrument will be tested automatically. Test results can be stored and printed automatically.Built-in real-time clock, the test date and time can be saved, displayed, and printed with the test results.Clean dry stack calibration functions. Measuring the capacitance and dielectric loss factor of the dry stack can determine its cleanliness and assembly conditions. Calibration data is saved automatically, facilitating the calculation of relative permittivity and DC resistivity.Main Technical IndicatorsPower supply voltage: 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 measured value + 0.5 pF)Relative permittivity: ±1% of measured valueDielectric dissipation factor: ± (1% of measured value + 0.0001)DC resistivity: ±10% of measured valueResolution:Capacitance: 0.01pFRelative permittivity: 0.001Dielectric dissipation factor: 0.00001Measured temperature range: 0~125°CTemperature measurement error: ±0.5°CAC test voltage (RMS): 500~2000V continuously adjustable, frequency 50HzDC test voltage: 0~500V continuously adjustablePower consumption: 100WExternal dimensions: 500×360×420 mmTotal weight: 22KgOperating ConditionsAmbient temperature: 0°C~40°CRelative humidity (RH): (see images for more details)Technical Specifications / FeaturesModel: HZJD-2ZBrand: HuazhengApplication: Measurement of dielectric loss and resistivity in insulating oils and liquidsDisplay: Large color LCD (800*480)Automatic measurement and storage/printing of resultsIntegrated structure with test cell, temperature controller, and moreComplies with GB/T5654-2007 standard
