SEL recently worked with Pend Oreille Public Utility District (PUD), an electric and water utility in Northeast Washington State, to upgrade an aging communications system with a simple and affordable solution.
Pend Oreille PUD began planning for an upgrade after their I/O boards started showing signs of failure. They understood that this could mean replacing all their field wiring, which would be difficult and time-intensive. SEL developed a custom cabling solution that allowed them to maintain the field wiring while exchanging their aging remote terminal unit (RTU) for an SEL Real-Time Automation Controller (RTAC) and replacing their old I/O equipment with the SEL Axion.
This video describes the communications solution and how Pend Oreille PUD is benefiting from improved built-in security, data integration and power system health visibility.
