Answer Posted / momenkasiu
Unity power factor means that Pf=1 or cos(phi)=1 so (phi)=0 where (phi) is the angle between the apparent power & active power in the power triangle so it means that the apparent power equals the active power and the reactive power in this case equals zero. No reactive power transmitted between the source and load which it exists only in the case of resistive loads.

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<
