DFT Insulating Oil Dissipation Factor Tester, Oil Tan Delta Tester
Transformer Oil Dissipation Factor Tester -- Model: DFT
Introduction:
DFT Transformer Oil Dissipation Factor Tester is a high-precision instrument, which can be applied to measure dielectric loss angle and volume resistivity of insulating oil.
Features:
- DFT Transformer Oil Dissipation Factor Tester is integrated by oil cup, temperature controller, 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.
