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 colcor 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. Measuring range! Electric capacity 5pF~200pF Relative Permittivity 1,000~30.000 Dielectric loss factor 0.00001~100 DC Resistivity 2.5MQm~20TQm Measuring accuracy! Electric capacity ± (1 % of measured value+0.5pF) Relative Permittivity ±1% of measured value Dielectric dissipation factor ± (1% of measured DC Resistivity ±10% of measured value •The test cell used of the three-electrode structure in line with the national standard GB/T5654-2007, with electrode spacing 2mm, can eliminate the effects of the stray capacitance and leakage on dielectric loss test results. The apparatus is equipped with the oil drainage solenoid switch, and we can empty the test cell in case of not removing it and rinse it with the test sample. •The instrument adopts the medium frequency induction heating, PID temperature control algorithm. This heating method has the advantages oft non-contact between the test cell and the heating body, even heating, fast speed, convenient control, strict control of the temperature within error range of the preset temperature. • Internal standard capacitor is SF6 gas-filled three-electrode capacitance, and its capacitor dielectric loss and electrical capacity is independent of ambient temperature, humidity and other effects, so that the instrument accuracy can be ensured even after prolonged use. •AC test power supply using AC-DC-AC conversion, effectively avoid the fluctuations in mains voltage and frequency on dielectric loss measurement accuracy effect. Even a generator, the instrument can work properly. •Perfect protection function; When there is over voltage^ over current or high-voltage short circuit, instruments can quickly cut off pressure, and issues a warning message. When the temperature of the sensor failure or not connected, the instrument will also issue a warning message. •There is a temperature limiting relay in the medium frequency induction heating furnace. When temperature above 120 degrees, the instrument frees the relay and stops heating. • More convenient the experimental parameter is set. Temperature setting range 0~125°C, AC voltage setting range 500~2000V, DC voltage setting range 0~500V.
