GE UR8FV universal relay CT/VT module
Functional characteristics:
Precise measurement: It can provide 3-1A/5A phase CT, 1A/5A ground CT and four-terminal voltage transformer for the relay, which can precisely measure current and voltage to ensure the effective operation of the electrical system. The current measurement accuracy can reach ±0.5% FS, and the voltage measurement accuracy is ±0.2% FS.
Signal monitoring: It can support up to 24 CT and VT analog signals, enhancing the monitoring capability of power lines. It can also detect faults caused by the condition of grounding conductors. Some modules have sensitive grounding protection functions. For high-impedance grounding systems, grounding fault protection can be achieved by obtaining sensitive grounding inputs.
Good compatibility: Designed to replace old modules or upgrade existing general-purpose relay systems, it is compatible with both new and old general-purpose relays. However, it is necessary to match the module with the corresponding CPU model to avoid incorrect indications on the display screen.
Technical parameters:
Input range: The input of the current transformer (CT) is 1A or 5A, and the input of the voltage transformer (VT) can support 115V, 230V, 460V or 575V.
Frequency range: 45-65Hz.
Power loss: CT is 0.05VA, VT is 0.5VA.
Operating temperature: -40°C to + 70°C.
Storage temperature: -40°C to + 85°C.
Application field:
Distribution system: It can precisely measure and monitor the current and voltage in the distribution lines, providing a guarantee for the stability and safety of power distribution, helping staff to promptly understand the operating status of the lines and prevent faults from occurring.
Energy management: In the process of energy production, transmission and consumption, it is used to monitor relevant electrical parameters, which helps to achieve rational allocation and efficient utilization of energy. It can be applied in places such as power plants and substations to monitor and control the current and voltage of equipment such as generators and transformers.
Industrial automation: It can be integrated into the control system of industrial automation production lines, such as PLC programmable controller modules or DCS system cards, to monitor the electrical parameters of production equipment, ensure the normal operation of the equipment, and also control the equipment based on the measurement results, achieving the automation and precision of the production process.
Renewable energy systems: In renewable energy power generation systems such as solar and wind power, it can be used to monitor the output current and voltage of power generation equipment, as well as the electrical parameters at the grid connection points, ensuring the stable connection and efficient operation of the renewable energy system with the grid.
Intelligent flat tempering furnace system manufacturing: It can monitor the electrical parameters during the operation of the flat tempering furnace in real time, ensuring the stable operation of the equipment and helping to improve the production quality and efficiency of tempered glass.
Intelligent fire water supply control system: It can monitor the current and voltage of motors and other equipment in the fire water supply system to ensure reliable operation of the system in case of fire and provide a stable water source for fire fighting work.
Constant flow computer control system for chemical plant liquid medicine: It can precisely measure relevant electrical parameters, provide accurate data support for the control of liquid medicine flow, ensure that the liquid medicine is delivered at a constant flow rate, and guarantee the stability of the chemical production process and product quality.
