A: Power factor e bolela karo-karolelano ea matla a sebetsang ho matla a bonahalang a potoloho ea AC.Thepa ea motlakase e sebelisoang ka tlas'a motlakase le matla a itseng, ha boleng bo phahame, molemo o betere, lisebelisoa tsa ho fehla matla li ka sebelisa ka botlalo.Hangata e emeloa ke cosine phi.
Boholo ba Power Factor (Power Factor) bo amana le mofuta oa mojaro oa potoloho, joalo ka bulb ea incandescent, sebōpi sa ho hanyetsa le tse ling tse hanyetsanang le matla a matla ke 1, ka kakaretso e nang le inductive load circuit power factor e ka tlaase ho 1. Power factor ke data ea bohlokoa ea tekheniki ea sistimi ea matla.Power factor ke ntlha e lekanyang katleho ea lisebelisoa tsa motlakase.Ntho e tlaase ea matla e bontša hore matla a sebetsang a potoloho a sebelisetsoang ho fetola matla a khoheli a maholo, a fokotsang sekhahla sa tšebeliso ea lisebelisoa le ho eketsa tahlehelo ea matla a motlakase oa mohala.Lipotolohong tsa AC, cosine ea phapang ea mohato pakeng tsa motlakase le ea hona joale (Φ) e bitsoa matla a matla, a emeloang ke letšoao la cosΦ.Ho latela lipalo, ntlha ea matla ke karo-karolelano ea matla a sebetsang le matla a bonahalang, ke hore, cosΦ=P/S.
Li-module tsohle tsa metering tsa matla tse ntlafalitsoeng le tse hlahisoang ke Gensi Technology li ka lekanya ka nepo lintlha tsa matla, joalo ka likarolo tse tharo tse kentsoeng matla a metering module JSY-MK-333 le module ea metering ea karolo e le 'ngoe ea matla JSY1003.
