What happen when ct secondary are open circuited? why same
thing is not happen in ordinary transformer?
Answer Posted / pritam upadhyay nit p
when secondary is open there ic no flux due to secondary
current to oppose flux due to primary so due to high flux
there is very high voltage induced on secondary side which
causes sparking and damage of core due to high flux demsity.
in case of power transformer flux is constant whtheer
primary open or not so there is no such case as in ct..

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<
