SR489-P5-HI-A20-E generator management relay
The SR489-P5-HI-A20-E is a generator management relay. Manufactured by GE Multilin for the 489 series, this relay is primarily used for monitoring, protection and control of generator systems. It is equipped with 5A phase CT assist and offers HI control power in the range of 90-300 VDC and 70265 VAC (48-62 Hz). In addition, the analog output on the relay is 4 to 20 mA with basic display function.
The relay has the ability to detect and judge faults with high precision, and can respond and deal with the faults and anomalies of the power system quickly to ensure the safe and stable operation of the power system. It is suitable for a variety of application scenarios, such as power plants, industrial power generation, and Marine and Marine engineering, to monitor the operating status of generators and protect generators from overcurrent, overvoltage, loss of power and other failures.
