Voltage drop compensator for electric distribution systems, uses switched secondary shunt device to generate correction which is applied to series transformer

摘要

The compensator has a switched-secondary transformer (110) across the incoming voltage (VE), with its output connected to a second transformer (118) in series between incoming and outgoing supplies to add a correction to incoming voltage. The compensator output voltage (VS) is measured (116) and applied to a controller (112), which selects switch position on the first transformer (110).
