Product Description
GDGY Capacitance & Resistivity Tester Insulating Oil Tangent Delta Tester
GDGY Insulating Oil Dielectric Loss Tangent Delta Tester is a high-precision instrument, which can be applied to measure dielectric loss angle and Volume Resistivity of insulating oil etc. 

GDGY Insulating Oil Dielectric Loss Tangent Delta Tester 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. 


Convenience and maneuverability are the most remarkable advantages of this instrument.

First of all, digital technology and intelligent automation measurement are applied inside the instrument.
Secondly, big-screen (240mm×128mm) menu interface in Chinese is equipped, with which user can be prompted each step during the operating process.
Thirdly, the result can be output by printer. The user can grasp operating processes masterly without technical training.
