Hi, this is amit kulkarni fm Ahmednagar,maharashtra india,
i do energy audit in various sector such as foundries, cnc shops,machine shops,forging,colleges etc.
power factor =Real power/active power.
to calculate origional PF
u require some data like
1.consumption of instrument in kwh (Ew)
2.consumption of reactive energy in kvarh (Eb)
3.working hrs.(t)
also u must know hp of insrument,rpm,efficiency.
Active energy power (P) = Ew/t.
origional pf = 1/√(Eb/Ew)+1 .
also u need any information @ power factor or energy saving pl mail me on powercop.auditors@gmail.com or powercop.general@gmail.com
