Product Description

GDGY 

Automatic Insulating Oil Tan Delta Resistivity Tester 





Introduction


  • GDGY Automatic Transformer Oil Tan Delta Resistivity 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.

Features


  • GDGY Automatic Insulating Oil Tan Delta Resistivity Tester has a high degree of automation. The heating of the oil cup, the measurement of dielectric loss and electrical resistivity can be completed in one test without personnel involvement in the whole process.

  • GDGY Automatic Insulating Oil Tan Delta Tester has a complete protection mechanism, with protection and reminding functions such as opening the lid and breaking high pressure, short circuit of the high and low voltage electrodes of the oil cup, empty burning of the heater without oil cup, and temperature sensor disconnection failure.

  • The oil cup adopts a three-pole structure, and the distance between the electrodes is 2mm, which can eliminate the influence of stray capacitance and leakage on the dielectric loss test results

  • Equipped with a large touch screen (320*240); all digital technology, all intelligent automatic measurement, multiple modes of measurement, window menu, concise and clear;

  • Build-in Micro Printer, the test results are automatically printed.
