Chapter Abstract:
One of the main keys of power quality is the voltage. Many people translate the power quality as voltage quality. This chapter describes the various types of voltage variations and how to deal with each type. Voltage sags are mainly caused by phenomena leading to high currents, which in turn cause a voltage drop across the network impedances with a magnitude that decreases in proportion to the electrical distance of the observation point from the source of the disturbance. The transient overvoltages are classified into two types: impulse transients and oscillatory transients. As the power demand increases, the voltage drop and losses are increased since the voltage drop is proportional to the demand current, and losses are proportional to the square of demand current. It is important to estimate these losses as accurately as possible to achieve good planning and high system performance.
