GE 489-P1-HI-A1-T generator monitoring relay

GE 489-P1-HI-A1-T generator monitoring relay

Functional characteristics
Comprehensive protection function: has a variety of protection functions for generators, including but not limited to over current protection, over voltage protection, under voltage protection, reverse power protection, loss of magnetic protection, ground fault protection. These protection functions can quickly detect various abnormal conditions during the operation of the generator, and take appropriate protective measures in time, such as sending an alarm signal or triggering a trip to protect the generator from damage.
Powerful measuring and monitoring function: it can accurately measure a variety of electrical parameters of the generator, such as voltage, current, frequency, power factor, active power, reactive power, etc. At the same time, it may also have the harmonic monitoring function, which can monitor the quality of the output power of the generator, and timely discover the harmonic problem in the power, which helps to ensure the power quality and the stable operation of the generator.

Data recording and analysis: The operation data of the generator can be recorded, including the change trend of electrical parameters, event records (such as protection action events, failure time, etc.). Through the analysis of this data, users can better understand the operation of the generator, troubleshoot and predictive maintenance, detect potential problems in advance, reduce downtime, and improve the reliability and service life of the generator.
Communication function: Usually supports a variety of communication protocols, such as Modbus RTU, etc., to facilitate communication with the upper computer monitoring system, DCS (distributed control system) or other intelligent devices. Through the communication network, users can realize the remote monitoring, parameter setting and fault diagnosis of the generator, which improves the automatic management level of the power generation system.
Friendly man-machine interface: equipped with an intuitive front panel display, which may be an enhanced LCD display, can clearly display the operating status of the generator, measurement parameters, fault information, etc. At the same time, it is equipped with operation buttons to facilitate users to set parameters, debug functions and view related information locally.

Application scenario: It is mainly used in various generator systems, including induction generators and synchronous generators in power plants, industrial self-provided power stations, substations and other places. It can provide comprehensive protection and monitoring for the generator to ensure the safe and stable operation of the generator under various operating conditions, improve the reliability and efficiency of the power generation system, and reduce maintenance costs and operational risks.
