Why generally the transformer primary is connected in star
& secondary in delta

Answer Posted / raul

its absolutely wrong dat most of d times the primary is
star connected and sec is delta connected...........the
connections depends upon d type of service
required........i.e star-delta is used as step down
transformer, delta-star as step up transformer.........star-
star is rarely used until required due to disturbance
caused in d neighbouring communication system .......

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<
