Thyristor-Controlled Automatic Voltage Regulator

Supplier From China
Sep-11-09

The TVR thyristor automatic feeder voltage regulator is used primarily on medium-voltage distribution lines. In TVR, power electronic on-load tap changing switches are employed in place of those used in the SVR feeder voltage regulator, resulting in quicker regulation and more frequent operation, ideal for distribution lines with severe voltage fluctuations and/or longer lines. TVR can maintain the power feeding voltage at desired level, reduce power loss over the line, thus improving power supply quality significantly.
