Product description:
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.
