2. Equipment Description:

HYGY Digital Automatic Dielectric Dissipation Factor 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. 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.
