Introduction:
GDGY 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.

GDRZ-902 Transformer Sweep Frequency Response Analyzer
Introduction:
The structure and reference of the transformer is fixed after been made, Therefor, the frequency
response of each winding will be almost the same normally;
Some case such as cut off between circles or phases in experience, cut off or winding moved for the
pull of power in running, winding moved for hit in transportation, could change the reference of the
transformer ,of which the frequency response will be changed, we could detect the deformation
according to the frequency response curve;
Our company has designed the winding deformation tester base on the idea and the advanced technique;
It could draw the frequency response curve accurately. Then we compare the curves horizontally or
vertically to detect the deformation of the transformer;
