Automatic Voltage Regulators

Mesa acted as the Responsible Engineer and provided design and engineering services to replace the existing Automatic Voltage Regulators (AVRs) at a coal fired plant for a Major Southern Utility Company. The new AVRs helped to maintain a constant fixed voltage output and stabilized the voltage of generators at variable loads. In order to provide redundancy for component failure, the new AVRs were installed in a two-section Digital Excitation Control System (DECS) cabinet, along with redundant power supplies.
