Dielectric tester EPOL60

dissipation factorinsulation oilnon-contact

EPOL60 Automatic Oil Dielectric Loss Tester, is used for measuring dielectric dissipation factor and DC resistivity of insulating oil and other insulating liquids. The instrument integrates with test oil 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. Features: -The Oil vessel adopts the three-electrode structure according to standard IEC 60247:2004, with electrode spacing 2mm, which can eliminate the effects of the stray capacitance and leakage on dielectric loss test results. -The instrument adopts the medium frequency induction heating, PID temperature control algorithm. This heating method has the advantages of non-contact between the test cell and the heating body, uniform heating, fast speed, convenient control, and strictly 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 are not affected by ambient temperature, humidity etc, so that the instrument accuracy can be ensured even after prolonged use. -AC test power supply uses AC-DC-AC conversion, which effectively prevents the fluctuations in mains voltage and frequency from affecting the dielectric loss measurement accuracy. Even use 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 high voltage, and issues a warning message.
