SL-OA28 Dielectric Loss and Resistivity Tester for Insulating Oil
Product description
INSULATION OIL DIELECTRIC LOSS TESTER 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.
All-digital technology is adopted in the instrument, all of which are intelligent and automatic measurement, and various modes of measurement. It is equipped with a 7-inch large-screen touch-control color screen display and a full Chinese menu. Every step is prompted in Chinese, and the test results can be printed out, so that operators can use it skillfully without professional training.
