Answer / Pradeep Singh

Harmonics are sinusoidal waves with frequencies that are integer multiples of the fundamental frequency in an electrical power system. They're typically produced by non-linear loads like rectifiers, variable speed drives, and some types of LED lighting. To control harmonics, you can use harmonic filters, capacitor banks, or active power filters.

when the supply of MSEB is cut off & all the load of the industry is driven on generator at that time the capacitor which is connected in industry for power factor control is switched off why?
