alfanar’s AVR (Automatic Voltage Regulator) or AVC (Automatic Voltage Control) panels are advanced control systems designed to maintain stable voltage levels across electrical networks. By automatically adjusting transformer tap positions, typically via On-Load Tap Changers (OLTCs), these panels ensure consistent power quality, protect sensitive equipment, and support grid reliability under varying load conditions. Ideal for substations and industrial facilities, AVR/AVC panels automate voltage regulation, reducing the need for manual intervention and enhancing operational efficiency.
