generally the resistance of armature is very small i.e in
term of .05ohm or like this.this is due to reduce the
losses.if the motor is connected direct supply high current
will flow and it may burn the armature winding.thats why
starter is connected between supply and motor which reduces
the starting current and provided smooth operation

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
For example-O/L protection setting have a range of
Time delay SC protection have a range of
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<
