This is the most advanced automatic version of the c&df sets within our product range. The automatic 12kv 200ma test set integrates the high voltage power source and the measuring bridge into one single compact unit. It is designed to measure dissipation factor and capacitance in heavy electromagnetic interference environment such as in power plants and substations. Using digital filters it eliminates interference signal to specimen signal by a ratio as high as 2:1. It can also be used in laboratory for high accuracy tests on high voltage bushings, transformer windings, shunt reactors, current transformer, capacitor voltage transformer (cvt), grading capacitors of circuit breakers, surge arrestors and generator windings.

PE-AOBDV Automatic Oil Breakdown Voltage Testeris a highly precise instrument, which can be applied to measure either the breakdown voltage or also check the withstanding voltage for a predefined time. Usual available automatic test sets only perform the former function, but PE-AOBDV can do both. PE-AOBDV can measure the breakdown voltage repetitively and computes an average reading, for a proper decision making. PE-AOBDV consists of an integrated Oil Cup, HV AC power source.
