GE UR8FH Multilin series CT/VT modules
Functional characteristics: It provides three 1A/5A phase current transformers, one 1A/5A ground current transformer and four voltage transformer terminals for the relay, which can reduce the voltage and current values of the power system to a level that can be recognized and regulated by general relays, providing key data for relay monitoring and control. It can also conduct trend analysis and export of the data generated by the system.
Performance characteristics
Precise current and voltage measurement: It provides three 1A/5A phase current transformers, one 1A/5A ground current transformer and four voltage transformer terminals for the relay, which can reduce the voltage and current values of the power system to a level that can be recognized and regulated by general relays, providing key data for relay monitoring and control.
Flexible protection functions: It features multiple protection functions, such as overcurrent protection, undervoltage protection, overvoltage protection, etc. Additionally, custom protection functions can be set through programming to meet specific application requirements. In addition, the module is equipped with a fault locator, which can quickly identify faults within the system, facilitating rapid troubleshooting and maintenance.
High-speed data acquisition: It has a strong data acquisition capability, reaching a rate of 256 samples per cycle. It can monitor system events in real time and respond quickly, providing rapid and accurate protection for high-voltage power systems.
Strong communication capability: Supports multiple communication protocols such as Modbus TCP, IEC 61850 and DNP3, and can be seamlessly integrated with the existing control system to achieve remote monitoring and control. Meanwhile, it features a user-friendly interface, facilitating centralized monitoring and control of key equipment.
Reliable hardware design: Robust structure, capable of withstanding extreme temperatures, humidity, vibration and other harsh working environments, ensuring stable operation in various industrial scenarios. It adopts a modular design, which is convenient for component access and maintenance. Moreover, the programming and setting interfaces are friendly, reducing the difficulty of operation and maintenance.
Flexible configuration: It offers multiple voltage and current input options, allowing users to choose based on their actual needs. Users can also select different installation methods to optimize space utilization and installation convenience.
Technical parameters: The control power supply is 50-300VDC or 40-265VAC. The working environment temperature is generally required to be between 0 and 55℃. The relative humidity of the air should be less than 85% (without condensation), and it should be kept away from strong vibration sources.
Application field:
Power system: It can be used for the protection and control of high-voltage power systems, featuring functions such as overcurrent protection, undervoltage protection, and overvoltage protection.
