In the field of electrical engineering and maintenance, ensuring the reliability and efficiency of insulating oils is essential. The dielectric loss tangent tester for insulating oils becomes an indispensable tool for professionals dedicated to maintaining the integrity of electrical systems. This sophisticated device is designed to measure the dielectric loss, or tangent delta, of insulating oils, providing crucial information about the condition and performance of these essential materials.General DescriptionThe HZJD-2Z insulating oil dielectric loss and resistivity tester is designed and manufactured according to the GB/T5654-2007 standard on 'Measurement of relative permittivity, dielectric loss factor, and DC resistivity in liquid insulating materials.' 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 and combines a test cell, temperature controller, temperature sensor, dielectric loss test bridge, AC power supply, standard capacitor, high resistance meter, DC high voltage source, and other main components. The instrument uses full digital technology and features intelligent automatic measurement. It is equipped with a large full-color LCD screen (800*480), allowing each step to be performed precisely. Test results are stored and printed automatically, making it easy to use even without professional training.Main Functions and FeaturesThree-electrode test cell, compliant with GB/T5654-2007, with a 2 mm electrode gap, eliminates the effects of parasitic capacitance and leakage on dielectric loss test results. Equipped with a solenoid oil drain switch for easy emptying and rinsing of the test cell.Uses medium-frequency induction heating and PID temperature control algorithm. This heating method offers advantages such as no contact between the test cell and the heating body, uniform heating, high speed, practical control, and strict temperature control within the preset error margin.The internal standard capacitor is a three-electrode SF6 gas-filled capacitor, whose dielectric loss and capacitance are independent of ambient temperature, humidity, and other effects, ensuring measurement accuracy even after prolonged use.The AC test power supply uses AC-DC-AC conversion to avoid fluctuations in grid voltage and frequency, ensuring measurement accuracy. The instrument operates correctly even with a generator.Comprehensive protection function: in case of overvoltage, overcurrent, or high-voltage short circuit, the instrument quickly cuts off the pressure and issues a warning. If the temperature sensor fails or is not connected, the instrument also issues a warning.The medium-frequency induction heating furnace has a temperature limiting relay. When the temperature exceeds 120°C, the instrument releases the relay and stops heating.Convenient adjustment of experimental parameters. Temperature range: 0 to 125°C, AC voltage: 500 to 2000 V, DC voltage: 0 to 500 V.Large, backlit, clear LCD screen. Intuitive interface: simply follow the menu instructions in Chinese and enter the command for the instrument to perform automatic tests. Results are stored and printed automatically.Built-in real-time clock: the date and time of the test can be saved, displayed, and printed with the test results.Clean dry cell calibration functions. Measuring the capacitance and dielectric loss factor of the dry cell allows determining its cleanliness and assembly conditions. Calibration data is saved automatically, facilitating the calculation of relative permittivity and DC resistivity.Main Technical IndicatorsVoltage supply: AC 220 V ± 10%Power frequency: 50 Hz/60 Hz ±1%Measurement range:Capacitance: 5 pF ~ 200 pFRelative permittivity: 1.000 ~ 30.000Dielectric loss factor: 0.00001 ~ 100DC resistivity: 2.5 MΩ·m ~ 20 TΩ·mMeasurement 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: 0.01 pFRelative permittivity: 0.001Dielectric dissipation factor: 0.00001Measured temperature range: 0 ~ 125°CTemperature measurement error: ±0.5°CAC test voltage (RMS): 500 ~ 2000 V continuously adjustable, 50 Hz frequencyDC test voltage: 0 ~ 500 V continuously adjustablePower consumption: 100WExternal dimensions: 500×360×420 mmTotal weight: 22 kgOperating ConditionsAmbient temperature: 0°C ~ 40°CRelative humidity (RH): (see images for details)Technical Specifications / FeaturesModel: HZJD-2ZBrand: HuazhengApplication: Measurement of dielectric loss and resistivity in insulating oils and liquidsDisplay: Large full-color LCD (800*480)Automatic measurement, storage, and printing of resultsIntegrated structure with test cell, temperature controller, and digital technologyMultiple safety and calibration features
