FSJS automatic tan delta tester is an automatic instrument, designed to measure capacitance and tan delta for all kinds of HV electric products, such as insulation materials, bushings, transformers, cables, capacitors and etc. Compare with schering capacitive bridge, it has the advantage of easy operation, automatic measurement, direct reading, no-required conversion, high precision, anti-interference and ect.

There are standard capacitor and step-up voltage equipment inside, using in internal mode, doesn’t need other devices, easy to carry.
