Eaton’s automatic source transfer (AST) solutions protect critical loads that cannot tolerate a sustained loss-of-voltage event. Through rapid communication and flexible, user-selectable restoration options, the solution helps utility companies to dramatically minimise service disruptions and quickly re-energises key customers. AST is one of Eaton’s grid automation system solutions.
| HIGH-SPEED, PEER-TO-PEER PROTOCOL |
Enables transfer to an alternative source in as few as six cycles, ensuring minimal service disruption PeerComm protocol enables the two reclosers to maintain constant communication |
| FLEXIBLE, USER-SELECTABLE RESTORATION OPTIONS |
Helps utility companies to quickly return systems back to normality after the return of the primary voltage source Local restoration enables each control to be manually operated Automatic restoration/manual initiation enables restoration to the preferred source to be manually initiated from either control Automatic restoration/automatic initiation enables restoration to occur once the preferred feeder voltage returns |
| MINIMISED VOLTAGE-SENSING REQUIREMENTS |
Only source-side voltage sensing is required for each recloser Eliminates redundant measurements and unnecessary data |
| FAST TRANSFER TIMES |
Allows source transfer to occur before back-up power is required, including generators |
