Oil dielectric loss tester is a high-precision instrument, which can be applied to measure dielectric loss angle and Volume Resistivity of insulating oil etc. It is integrated by oil cup for dielectric loss, temperature-control equipment, temperature sensor, test-bridge for dielectric loss, AC trial electrical source, standard capacitor, high resistance meter and DC high-voltage power etc. The most advanced heating mode of high frequency induction is applied to the heating part of this instrument, which has the advantage of non-contact of oil cup and heating unit, homogeneous heating, quick velocity and convenient control etc.

Technical index#65306;

Oil cup technical specifciations:

#9332; Distance between High Voltage terminal

and Low Voltage terminal 2mm

#9333; Capacitance of Empty Cup 60±2PF

#9334; The Highest testing voltage Industrial Frequency 2000V

#9335; Dielectric Loss of Empty Cup tg#948;#65308;1×10-4

#9336; Liquid capacity About 40ml

#9337; Electrode Material Stainless Steel

Advantage#65306;

AC-DC-AC conversion mode is applied to AC trial electrical source so that the problem how to measure correctly under the fluctuation of voltage and frequency can be avoided. Even when the electric generator is working, the instrument can operate correctly. The inner standard capacitor is SF6 three-pole inflate capacitor, whose dielectric loss and capacitance is not influenced by environmental temperature and dampness etc. In this way, the accuracy of the instrument is guaranteed conformably after a long-time application.
