General Electric (GE) recently introduced a new generator management relay, the SR489-P5-LO-A20-E, as part of the GE Multilin 489 family, designed to provide comprehensive protection and control capabilities for induction or synchronous generators. This relay is designed to ensure the safe and stable operation of the generator under a variety of operating conditions and is capable of operating at frequencies of 25, 50 or 60 Hz
.

Product features:

Comprehensive protection: The SR489-P5-LO-A20-E monitors a variety of operating parameters such as voltage, current, frequency and power factor of the generator, and alerts or takes protective measures when abnormal conditions are detected.
Fault diagnosis: Built-in self-diagnosis function can quickly locate the fault, convenient maintenance personnel to repair.
Communication capability: Support RS485 communication port and ModbusRTU or DNP 3.0 protocol to achieve remote monitoring and control.
Flexible configuration: It can be flexibly configured according to different generator types and operating conditions to meet various application requirements.
