Dielectric dissipation factor is also known as loss factor or tan delta of transformer oil. When a insulating materials is placed between live part and grounded part of an electrical equipment, leakage current will flow.
GDGY Digital Automatic insulating oil tan delta tester is a
high-precision
instrument,
which can be applied to measure dielectric dissipation factor 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.
It adopts the advanced heating system, high frequency induction heating, which is heating fast , homogeneous.
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.
