PF = VI cosφ

Power = VI cosφ

where cosφ is also called power factor

If you know the power consumed by the load (put an KW Meter) then you can calculate PF

else you can put directly pf meter in your line.

Well , working in a factory has its advantages- get free time in between - when people take tea/ lunch braks etc (my lunch in canteen in over in 10 min max) so the other time i use for these knowledge expansion activities.

Answering these brushes up my cobweb.

And other things enlarge my knowledge base (so many things still to learn).

And best is it is end of fin year - so on in duty for about 16 hrs+/day and no sunday off either. .

Another 3 weeks of it
