why do we generate sinusoidal ac?can we generate some other
waveforms by alternators?
Answer Posted / fonzy umali
ALTERNATOR CAN ONLY GENERATE SINE WAVE THAT IS..0 TO 180
THEN 180 TO 360 DEGREES. DERIVE FROM THE ROOT WORD
ALTERNATOR MEANS IT VARIES FROM POSITIVE TO NEGATIVE WAVE
OR VICE VERSA..IT MIGHT PRODUCE RIPPLE DURING WHICH STATICS
OR HARMONICS BUT IT ALWAYS HAVE POSITIVE AND NEGATIVE WAVE.

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<
