NRSH-C Insulating Oil Tan Delta Tester

NRSH-C Insulating Oil Tan Delta Tester also names as oil dielectric loss tester it is designed by our company according to IEC and the relevant national regulations it is a high-precision digital industrial equipment. The instrument adopts high-frequency induction heating technology uniform heating fast heating speed and short time. Using single chip microcomputer to control and calculate to achieve automation high measuring accuracy of capacitance and dielectric loss stable data and good repeatability. The output voltage 0~2000V can be adjusted continuously which is suitable for various voltage requirement of different tested objects. Widely used in dielectric loss measurement of transformer oil capacitor oil and cable oil.
