Product Description

GDGY Automatic Transformer Oil Dielectric Loss Resistivity Tester

Why do we use tan delta test of transformer ?

The main purpose of the tan delta test is to make sure of maintaining a secure and reliable functioning of the transformer. With the calculation of dissipation factor and capacitance values, it provides the result of insulation behavior of bushings and in windings too.

Abstract of GDGY transformer oil dielectric loss resistivity tester:

* It is a high-precision instrument, which can be applied to measure tan delta, dielectric loss angle and volume resistivity of insulating oil automatically. 
 
* 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.
