D-S-phase single-phase oil-immersed self-cooled J-L-S copper wire windings for the aluminum Z-load tap

single-phase S D - - 3 - Oil Baptist Church sang J self-winding cold L S copper wire line is aluminum Z --carrier

Power factor big and small and circuit load nature related, like resistance load and so on incandescent lamp bulb, resistance furnace power factors are 1, generally has the inductive load electric circuit power factor all to be smaller than 1.The power factor is an electrical power system important
