SL-OA28 Dielectric Loss and Resistivity Tester for Insulating Oil
Product description
INSULATION 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. 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.
All-digital technology is adopted in the instrument, all of which
are intelligent and automatic measurement, and various modes of
measurement. It is equipped with a 7-inch large-screen
touch-control color screen display and a full Chinese menu. Every
step is prompted in Chinese, and the test results can be printed
out, so that operators can use it skillfully without professional
training.
