Answer Posted / lokesh raj
AN EXCITED OR OVER EXCITED GENERATOR PRODCUES COMPARETIVELY
HIGHER VOLTAGE AND HIGHER CURRENT, BUT FOR CONSTANT LOAD
V*I*Cos(angle) IS CONSTANT. AS VOLTAGE AND CURRENT IS
INCREASED V*I*Sin(ANGLE) THAT IS REACTIVE POWER.
AS THE EXCITATION INCREASED THE REACTIVE POWER INCREAED.

If short circuit ratio is high is it bad or good for a machine then tell the reason...
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<
