basically harmonics are the distorsion in the system waveform. these may lead to the poor sine wave and hence the system performance is effected. Harmonics are of two types : even harmonics and odd harmonics. Compared to even harmonics odd harmonics are very dangerous. if in a one half cycle of the main wave there are 3 half cycles, then it is 3rd harmonic. and similarly if in one half cycle of the main wave there are 5 half cycles, then it is 5th harmonic. the above said are odd harmonics. similarly for even harmonics, there will be even no of half cycles for each half cycle of the mainn wave.

why inductivedrop in dc motor neglected
what is the speed of mixie?
IN THE CASE OF AN ELCB, IF THERE IS ANY UNSTABILITY BETWEEN PHASE AND NEUTRAL IT MAY TRIP. BUT MY QUESTION IS WHEN A LOAD IS CONNECTED IN BETWEEN P AND N, THE LOAD CONSUMES SOME POWER AND THERE IS A DIFFERENCE IN NEUTRAL WITH RESPECT TO THE PHASE. THUS ACCORDING TO ME, THE ELCB WILL AUTOMATICALLY OPERATES WHEN EVER THE LOAD CONSUMES-- I KNOW IT IS WRONG. BUT THE SOLUTION IS?????????
