what is the need of representing AC power in sinusoidal
waveform? why not in square or rectangular etc...

Answer Posted / m u shetty

in alternator the voltage and current produced varies with
respect to time as represented by sinewave That is why it
is represented as sine wave We cant produce voltage other
than sinesoidal waveform from alternator However if produce
whichever form of waveform required using electronic
components and by properly designing the circuit

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<
