STEPVOLTAGE REGULATORS IN THE UTILITY DISTRIBUTION ...
· Moreover, modern controllers are equipped with data acquisition and communiion capabilities for remote appliions. Utility stepvoltage regulators usually allow a maximum voltage regulation range of ±10% of the incoming line voltage in 32 steps of 5/8% or %. That makes 16 steps each for buck and boost – 5/8% x 16 steps = 10%.
