[CN] Integration of sophisticated oil-loss volume resistivity Tester Dec 1, 2015
integrated precision oil dielectric loss volume resistivity tester is used insulating oil liquid and insulating medium of dielectric loss Angle and the volume resistivity testing of high precision instrument. Light weight, small size, testing the safe operation, one thing amphibious, portable integrated structure. Internal integration: dielectric loss oil cup appliace meter, temperature sensors, dielectric loss to test a bridge, communication high-voltage test power supply, standard capacitor, high resistance meter, dc high-voltage test power supply, major components. One heating part adopts the most advanced high frequency inductive heating mode, this heating mode with oil cup and heating body non-contact, heating uniform, speed is quick, convenient control etc. Exchange test power adopt AC - DC - AC conversion mode, effectively avoid mains supplyicoil voltage and frequency fluctuation on the dielectric loss to test accuracy effect, even generator power generation, the instrument can also run properly. The internal standard capacitors for SF6 inflatable three extremely type capacitor, this capacitance dielectric loss and electric capacity is not suffer environmental temperature, humidity and so on impact, ensure instrument after a long time a still precision consistent.
