How much buck and boost is a typical distribution step regulator capable of providing to the system?

A typical distribution step regulator is designed to maintain voltage levels within a specific range, providing the necessary adjustments to accommodate fluctuations in load demand and maintain power quality. The capability of a step regulator to buck (reduce) or boost (increase) voltage is crucial in keeping the distribution system functioning efficiently.

The correct choice indicates that a typical distribution step regulator can provide a buck and boost of up to +/- 10% of the applied voltage. This percentage allows the regulator to effectively manage the voltage levels within the acceptable limits, ensuring that the voltage supplied to consumers remains stable and within predetermined thresholds.

This adjustment range is particularly important in preventing utility customers from experiencing voltage that is too high or too low, both of which can cause damage to electrical devices or lead to inefficiencies. Therefore, the specified capability of +/- 10% is a standard range for most distribution step regulators, making it a crucial aspect of their operation in electrical distribution systems.
