GE 489-P1-LO-A1-E Generator management relay module

GE 489-P1-LO-A1-E Generator management relay module

Functional characteristics
Protection function: It can provide over current protection, under voltage protection, ground fault protection, differential protection, over/under frequency protection, loss of magnetic protection, synchronous inspection and other protection functions, which can effectively protect the generator from various electrical and mechanical faults.
Measurement and monitoring: It can accurately measure a variety of electrical parameters of the generator, such as voltage, current, frequency, power factor, active power, reactive power, etc., and may also have harmonic monitoring function to ensure power quality and stable operation of the generator.
Communication function: Usually support RS485, RS232 and Ethernet communication, using Modbus RTU, DNP 3.0 and other communication protocols, easy to communicate with the host computer monitoring system, DCS or other intelligent devices, to achieve remote monitoring, parameter setting and fault diagnosis.

The relay can accurately measure a variety of electrical parameters of the generator, such as voltage, current, frequency, power factor, active power, reactive power, etc., and has a variety of protection functions to provide comprehensive protection and real-time monitoring of the generator. At the same time, it supports a variety of communication protocols, easy to communicate with the host computer monitoring system, etc., to achieve remote monitoring and management.
