This is done by switching off some of the loads, usually the ones that are least essential.<\/p>\n<p>The other options are incorrect because:<\/p>\n<ul>\n<li>A. system power factor is changed. The power factor is the ratio of real power to apparent power. It is not changed during load shedding.<\/li>\n<li>C. system voltage is reduced. The system voltage may be reduced during load shedding, but this is not the main purpose of load shedding.<\/li>\n<li>D. system frequency is reduced. The system frequency is not reduced during load shedding.<\/li>\n<\/ul>\n<p>Efficiency is the secondary consideration in load shedding. The main consideration is to prevent a blackout.
