This magnetic field can cause losses in the conductor, which can lead to increased heating and decreased efficiency.

If the power factor is low, then the current will be higher than it needs to be, and the equipment will be underutilized. This can lead to increased costs and decreased reliability.<\/li>\n<li>To reduce voltage regulation of the line: Voltage regulation is the difference between the voltage at the sending end of a line and the voltage at the receiving end. The higher the power factor, the lower the voltage regulation, and the more efficient the line will be.<\/li>\n<\/ul>\n<p>Therefore, power factor is kept high to reduce line losses, maximize the utilization of the capacities of generators, lines and transformers, and reduce voltage regulation of the line.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe
