Automatic Voltage Regulating Relays (AVR) are essential devices used to maintain stable voltage output in generators, alternators, and industrial power systems. These relays continuously monitor voltage levels and automatically adjust excitation current to prevent over-voltage and under-voltage conditions. Designed for reliable performance in demanding environments, AVR relays improve power quality, protect electrical equipment, and enhance system efficiency. Suitable for diesel generator sets, control panels, substations, and transformer applications.
