Online Voltage Regulation System (AVC)
RUHSTRAT OLIVER AVC voltage optimization equipment operates like an online system, providing a new type of unstable power protection. This system can correct voltage deviations in real time (response time 140μs, correction time <5ms, usually within 2ms) and is easier to integrate into industrial facilities than uninterruptible power supply equipment. Compared to uninterruptible power supply equipment, the grid short-circuit capacity basically remains unchanged, and existing protective devices such as fuses and circuit breakers can continue to operate.

Working Principle
The online voltage regulation system consists of a rectifier, inverter, bypass protection thyristor switch, and injection transformer. Whether during normal operation or voltage sags, the system remains online in real time. When a voltage sag occurs on the system side, the rectifier and inverter inside the device generate a corresponding compensation voltage, which is injected into the original power supply system through the injection transformer, thereby achieving online voltage sag regulation. When an internal fault occurs in the online voltage regulation system, the bypass protection thyristor switch quickly (at the microsecond level) disconnects the regulation system from the power supply system.
