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.
