Product introduction

NRSH-C insulating oil dielectric loss tester 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.

Alternative name
Oil dielectric loss tester, insulating oil dielectric loss tester, oil dielectric loss tester, insulating oil dielectric loss test device
The Characteristics of the products

1. The instrument adopts high-frequency induction heating technology, uniform heating, fast heating speed and short time.

2. The output voltage 0~2000V can be adjusted continuously, which is suitable for various voltage requirement of different tested objects.
