What is the thumb rule for calculating the P.F correction
Capacitor?? Say for 100 hp motor how much micro farad
Capacitor is needed .... Thumb rule so quick answer wanted

Answer Posted / himanshu

Motor is an inductive load so it is consuming
active power that depends on its load and
reactive power that is consumed by motor to set up its
magnetic field it is constant so we should connect a
capacitor which consumes the negative reactive power
according to p.f. correction requirement.

When we use air circuit breaker, it has O/L protection ,time delay SC protection, Instataneous SC protection & ground fault protection. They all have some setting range. But what is the suitable/allowable setting for the above protection which will be safe for the equipment? For example-O/L protection setting have a range of (0.4,0.45,0.5,0.55,0.6,0.65,0.7,0.8,0.9,1.0)xIn Time delay SC protection have a range of (1.25,1.5,2,3,4,6,8,10,12)xIn Time delay setting is 0.02,0.1,0.2,0.3,0.4 Instataneous setting is fixed to 20xIn Gound fault setting is given 100A,300A,600A,900A,1200A This setting are for 2500A ACB. So what will be the basic allowable setting for the above protection? is there any formulae to calculate this<
