Catalog excerpts

Usage: It is used for measuring dielectric dissipation factor and DC resistivity of insulating oil and other insulating liquids. ■ The instrument adopts the medium frequency induction heating, PID temperature control algorithm. This heating method has the advantages of non-con-tact 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. Dielectric dissipation facto
