Description

The RVR-1 single phase automatic voltage regulator is a tap-changing autotransformer. This automatic voltage regulator adjusts distribution line voltage from 10% boost to 10% buck across 32 steps, each around 5/8%. It covers voltage ratings from 2400V (60kV BIL) to 34500V (200kV BIL), suitable for 50Hz and 60Hz systems.

Built with internal potential winding taps and external ratio correction transformer, the automatic voltage regulator adapts to multiple system voltages. Smaller kVA versions come with pole-mount support lugs and substation/platform fixing fittings; larger automatic voltage regulator units are equipped with substation bases for pad mounting.

Differences Between Linear Regulators, Switching Regulators, and Series Regulators

1.Linear Regulators vs. Switching RegulatorsA linear regulator requires an input voltage higher than its output voltage. It handles the difference between input and output voltages—known as the dropout voltage—by varying the impedance of its internal regulating element (such as a transistor).Think of a linear regulator as a precise “voltage control expert.” When faced with excessive input voltage, it decisively “acts” by “cutting off” the portion exceeding the desired output level, ensuring the
