GE 489-P1-HI-A20-T-H monitoring relay

GE 489-P1-HI-A20-T-H monitoring relay

Functional characteristics
Comprehensive protection functions: with a variety of protection mechanisms for generators, such as 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 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 measurement and monitoring capabilities: can accurately measure a variety of electrical parameters of the generator, such as voltage, current, frequency, power factor, active power, reactive power, etc. In addition, it may also have harmonic monitoring function, which can carefully monitor the quality of the output power of the generator, timely find harmonic problems in the power, ensure that the power quality meets the requirements, and ensure the stable operation of the generator and other power equipment.

Data recording and analysis function: Because of the T characteristic, the data recording and analysis function of the relay is more prominent. It can record the operation data of the generator according to a certain time interval or event triggering mechanism to form a detailed operation log. Through the analysis of these data, users can understand the long-term operation trend of the generator, identify potential problems in advance, develop a reasonable maintenance plan, and achieve predictive maintenance, thereby reducing downtime and improving the reliability and service life of the generator.
Flexible communication functions: Support a variety of communication protocols, such as Modbus RTU, DNP 3.0, etc., to facilitate communication with the upper computer monitoring system, distributed control system (DCS) or other intelligent devices. Through the communication network, users can remotely monitor the generator in real time, parameter setting and fault diagnosis, realize the automatic management and centralized control of the power generation system, improve the management efficiency and convenience.
Friendly man-machine interface: equipped with an intuitive front panel display, possibly an enhanced LCD display, which can clearly display the operating status of the generator, measurement parameters, fault information and other content. At the same time, it is equipped with operation buttons, which is convenient for users to set parameters, debug functions and view relevant information locally, and even non-professionals can easily operate and maintain.
