The AVR-3MT microprocessor-based automatic excitation regulator is designed for use as a part of excitation systems of all types manufactured by the Electrosila plant of OJSC Power Machines. The main purpose of the AVR-3MT regulator is to regulate voltage at the power plant bus bars, to increase static and dynamic stability limits of synchronous machines, to improve damping of oscillations in the power system. To improve reliability, the regulator is designed to operate in a redundant system. The regulator performs monitoring and interaction with the excitation system protections. The regulator equipment is located in the 6U42HP design. Warranty period - 36 months from the date of shipment to the plant "Electrosila".
