As we use capacitior bank in 3ph ckt for improvement of PF, why not we use capacitor in single phase domestric use, at our house their are many inductive equipments,like fan,mixer,tube choke,air conditioner they also draw PF... by using capacitor can they improve PF. if yes--what are advantage and how to connect a capactor in single ph,and which type of capacitor if no- what are disadvantages.862
what is the difference between H.T Or HV lines...?1 2345
As we use capacitor bank in 3ph ckt to improve PF, can we use capacitor in single ph domestric use, in house we have Fan,Mixer,electric cooker,iron,tube choke they also lag the system,because it is inductive load. if it is possible to improve PF of single ph system-- if yes- type of capacitor to be used,connection diagram, working in detail. if no-- list it.750
