Reliable Protection Capabilities: The REG216 delivers fast-acting protection with a tripping time of less than 10 ms for critical faults, ensuring minimal impact on the power system. Its advanced algorithm supports adaptive distance protection, which automatically adjusts impedance settings based on network topology, reducing the risk of false tripping or delayed responses.
Modular and Scalable Design: The device’s modular architecture allows for easy expansion of I/O modules, making it adaptable to both simple and complex system requirements. This flexibility simplifies upgrades and retrofits, ensuring the REG216 can grow with evolving grid needs.
Enhanced Connectivity and Diagnostics: With native support for IEC 61850, the REG216 enables seamless integration into digital substation environments. Its built-in phasor measurement unit (PMU) functionality provides accurate synchrophasor data for system-wide stability analysis. The device also offers comprehensive self-diagnostics, including hardware health checks and firmware version management, to minimize maintenance efforts and improve operational efficiency.
Cybersecurity Compliance: Designed with cyber threats in mind, the REG216 incorporates secure communication protocols and encrypted data transfer, complying with international standards for power system cybersecurity. This ensures protection against unauthorized access and data breaches, critical for maintaining grid integrity in interconnected networks.
The ABB REG216 is widely deployed in medium-voltage (MV) power systems across various industries, including utilities, oil and gas, manufacturing, and renewable energy. In utility networks, it serves as a primary protection device for feeders, transformers, and generators, ensuring reliable power distribution to residential and commercial consumers. In industrial settings, such as manufacturing plants or mining operations, the REG216 safeguards critical equipment from overloads and faults, minimizing production interruptions and extending asset lifespan.
For renewable energy applications, the REG216 plays a key role in integrating solar farms, wind parks, and energy storage systems into the grid. Its adaptive protection features can handle the variable power flows and transient conditions inherent in renewable energy systems, ensuring stable operation and grid compliance. Additionally, the device is suitable for use in digital substations, where its IEC 61850 compatibility enables interoperability with other smart devices, supporting the transition to fully automated and data-driven power infrastructure.
