An overview,

ZY7820 empty load tester is my company's r & D personnel specifically for bad power users to evade the basic electricity bill, privately increase the capacity of the problem and r & D design of the new instrument, is specially used for transformer capacity, characteristic parameter measurement of high precision instrument. This product adopts color large LCD display, Chinese display, simple and quick menu operation, friendly man-machine interface. The instrument has a rechargeable battery inside, which can work without external power supply. Battery a complete charge can be continuous measurement of 500 sets of transformers. In addition, the instrument can provide three-phase precision 50Hz sine wave AC test power supply, in the measurement of transformer capacity and transformer load loss without external three-phase test power supply and voltage regulator, current booster and other auxiliary equipment, so as to greatly improve your work efficiency.
