i heard that power factor(PF) is the main concern for industries, if they are maintaining PF around 0.6 they will be fined for that. now the question is, how can they improve the PF ranging between 0.9 to 0.95 which is safe for them i,e escaping from the fine?5 5797

how can calculation ate Amps for cabel. Ex-for 1sqmm wire hou many amps we can draw
How npn and pnp transistor works
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.

In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
