Description
Legacy compact digital excitation (service).
Did you know
- The ABB UNITROL 1000 series of automatic voltage regulators (AVR) was launched in the year 2000. It builds on ABB's extensive heritage in excitation systems, with over 125 years of experience in design, manufacturing, and testing.
- The UNITROL 1000 series is positioned as ABB's compact and reliable AVR solution for low to medium power range applications, specifically for synchronous machines from 100 kVA to 80 MVA. This places it below the UNITROL 6000 series, which is designed for larger power plants and demanding industries with excitation currents up to 10,000 A, and the UNITROL 8000, which handles excitation currents up to 2,000 A.
- The UNITROL 1000 is chosen for its compact and robust design, making it suitable for harsh industrial environments and installations where space is critical. It offers stable and accurate voltage regulation with fast response to load changes, ensuring high-quality power and compliance with global grid codes.
| Model | Continuous Excitation Current | Generator Size (MVA) | Key Features |
