Voltage variations can adversely affect utilities and their customers, leading to customer complaints, revenue loss from sub-normal voltage, and increased costs due to higher line losses. Ideally, distribution lines should maintain constant voltage along the entire line. However, in reality, impedance in the distribution line causes voltage discrepancies between the end and terminal points. The actual voltage deviating from the rated voltage of the circuit size serves as a critical indicator of power quality and reliability. To address this issue, three-phase voltage regulators are employed at the end of transmission lines to ensure that the power supply voltage remains at the rated level.
