we have two 11/.433 kv. distribution Transformer rating as
1000 kva & 500 kva , i wants to run parallel both transformer.
both transformer impendence voltage is 5.24%, How can we run
both t/f, & how sharing the load

Answer Posted / virendra

As mentioned if the capacity, the vectror group ,
Impedance is equall you can connect both the transformet
in parrel just make sure that the Phase sequence for both
the transformer is same at the time of parallel & as the %
impedance is same the laad sharing will be equall.

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<
