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.
