two distinct types of auto load booster

Applied in the utility’s distribution systems are generally medium-voltage mechanical high voltage auto load booster (SVR). It should be noted that there are two distinct types of AC auto load booster: Medium-voltage step voltage regulator(mechanical) and the Low-voltage step voltage regulator(mechanical or electronic). The difference in their operation and design clearly demonstrate that their applications are not the same. The latter is intended to protect end-user devices from overvoltage and undervoltage conditions.
