Answer Posted / krishna.bagavan
for 12mva at 0.8 pf mw= 0.8 x 12 mva
= 9.6
as per p.f.triangle mvar=square root of mw2+mva2
ie. square root of 9.6 x 9.6 + 12 x 12.
= square root of 92.16 + 144
=square root of 236.16
=16 mvar

Is there any type of starter for DC motor other than two point,Three point and Four point starters?
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<
