Before doing mathematical manupulaion,as expaines very well
by our answer poster Dinesh.
Lets understand this simple fact that the power factor
changes due to the variation in Reactive power only.With
the help of power factor, one can easily calculate Reactive
power(Q=P*tan(arc cos pf)). The difference between reactive
power at two power factors is supplied by capacitor.

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<
