GE relay protection devices are widely used in power systems. The following is a related introduction:

Product Series GE's UR series is a well-known product1. It includes line protection (D30, D60, L60, L90), generator protection (G30, G60), feeder protection (F35, F60), motor protection (M60), transformer protection (T35, T60), busbar protection (B30, B90), controller (C30, C60) and other functional units1. Features and Advantages High reliability: With advanced hardware and software design, it can work stably in harsh environments and provide long-lasting protection and control for power systems. By quickly detecting faults and anomalies, it can quickly isolate faults, prevent cascading faults, reduce power outage time, and ensure stable power supply. Multi-function protection: It has a variety of protection functions, covering overcurrent, overvoltage, undervoltage, frequency deviation, differential protection, etc., which can fully protect all parts of the power system from fault damage. Flexible configuration: It provides a wealth of configuration options and can be customized according to specific application requirements. With programmable logic functions and parameter settings, it can be flexibly adjusted according to the characteristics and requirements of the power system. Strong communication capabilities: supports multiple communication protocols, such as IEC 61850, Modbus, DNP 3, etc., and can be seamlessly integrated with substation automation systems and other control equipment to achieve data interaction and remote control. Easy to maintain 1: Adopting a modular structure, such as the UR series is a 19-inch 4RU high module, which is a pluggable structure, easy to upgrade and maintain, and reduces the number of spare parts and maintenance costs. The URPC software equipped has functions such as event analysis, vector and waveform reproduction, and real-time data collection, which simplifies the setting and maintenance of the device. Working principle GE relay protection devices monitor the current, voltage, frequency and other parameters of the power system in real time through built-in precision sensors and intelligent algorithms. When it is detected that the parameters deviate from the normal range or a fault feature occurs, the device will quickly send a trip signal according to the preset protection strategy and logic to cut off the fault circuit to protect the safety of power equipment and systems. Application field Widely used in various links of power systems such as power generation, transmission, and distribution. In power plants, it is used to protect generators, transformers and other equipment; in substations, it protects and monitors busbars, feeders, etc.; in the industrial field, it provides reliable relay protection for motors, large equipment, etc.
