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.

SVR automatic feeder voltage regulator is tracking the variation in feeder voltage and changing the turn ratio of the built-in transformer, thus maintaining its output voltage within the permissible range. SVR functions satisfactorily when its input voltage fluctuates within 30% of its rating, ideal for feeder lines with large voltage drops and/or voltage fluctuations. Installed at the medium or receiving end of a feeder, SVR can effectively keep the user voltage at desired level and reduce power loss over the line. Moreover, SVR can also be applied to substations without on-load tap-changer transformers. Installed at the outgoing-line-side in such substations, SVR maintains the outlet bus voltage at specified values.
SVR has been patented for its originality (Patent NO 02 2 92527.9) and received certificates as follows:
