Description

The 489-P1-LO-A20 is a model of Generator Management Relay (GMR) manufactured by General Electric (GE). A Generator Management Relay is a device that provides protection and control functions for a generator in a power system. It is responsible for monitoring various parameters, such as voltage, current, frequency, and phase angle, to ensure that the generator operates within safe limits and doesn't cause any damage to itself or the power system. The 489-P1-LO-A20 GMR is a microprocessor-based relay that provides advanced protection and control functions for generators. Some of its key features include: Overcurrent protection Under/overvoltage protection Under/overfrequency protection Loss-of-field protection Reverse power protection Synchronization check Automatic voltage regulator (AVR) control Ethernet communication capabilities This GMR model is designed for use in low-voltage applications and can be used in a variety of generator types, including synchronous generators, induction generators, and wind turbines. It is commonly used in power generation facilities, industrial plants, and other applications where reliable generator protection and control is critical.
