REF615 HBFFAEAGNBA1ANB1XD
REF615 HBFFAEAGNBA1ANB1XD Feeder Protection and Control Module
Product Description
The REF615 HBFFAEAGNBA1ANB1XD module, developed by ABB, is a highly sophisticated and dedicated device in the Relion® product family, specifically designed for comprehensive feeder protection and control within utility substations and industrial power systems. It plays a crucial role in safeguarding and managing power distribution networks, whether they are radial, looped, or meshed, even in the presence of distributed power generation sources.
In utility substations, this module serves as a vigilant guardian, continuously monitoring overhead lines and cable feeders. It can accurately detect and respond to various electrical faults such as overcurrents, earth faults, and voltage irregularities. For example, in a large urban power distribution network, it can quickly identify an overcurrent situation caused by sudden load surges in a particular feeder section. Once detected, it immediately takes appropriate protective actions, such as tripping the relevant circuit breakers, to prevent equipment damage and power outages, ensuring the stable and reliable operation of the entire power grid.
In industrial power systems, like those in a large manufacturing plant, the REF615 module not only provides protection but also enables precise control. It can be integrated with the plant’s overall automation system to regulate the power supply to different production lines based on their real-time power demands. This helps in optimizing energy consumption, improving production efficiency, and enhancing the overall safety and reliability of the industrial power infrastructure.
The module is engineered with a compact and withdrawable unit design, which not only saves valuable space in control cabinets but also facilitates easy installation, maintenance, and replacement. It features a large graphical display that can present customizable single-line diagrams (SLDs), allowing operators to visually monitor the power system’s status at a glance. The display can be accessed locally on the module itself or remotely through a user-friendly web-browser-based human machine interface (HMI), providing flexibility for operators to manage the system from different locations.
Product Parameters
Electrical Parameters
- Rated Voltage: 85 – 264V AC/DC, providing wide compatibility with different power supply systems. This wide voltage range ensures stable operation in various electrical environments, whether in regions with different standard grid voltages or in industrial settings with specific power supply requirements.
- Rated Frequency: 47 – 63Hz, suitable for use in power systems operating within the common frequency ranges globally. It can adapt to both 50Hz and 60Hz power grids without performance degradation.
- Rated Current: 0.5A (measurement and protection current rating), which is designed to accurately measure and protect against abnormal current conditions in the feeder circuits. This current rating is calibrated to ensure reliable detection of overcurrents and other current-related faults.
- Contact Current: 0.5A DC rated value peak AC resistance. The contacts are designed to handle this current while maintaining reliable electrical connection and disconnection during normal and fault conditions.
- Contact Switch: 200 VDC peak. The contacts are capable of switching high-voltage DC loads, ensuring effective isolation and control in DC power systems.
