Automatic Source Transfer (AST)
Cooper Power Systems Automatic Source Transfer (AST) application automatically transfers to an alternate source for critical loads when a loss of voltage event occurs. Form 6 controls communicate via PeerComm, Cooper’s high-speed, peer-to-peer protocol. Multiple communications options are available, allowing reclosers to be several miles apart. Automatic Source Transfer allows Form 6 controls to retain their overcurrent protection capabilities.
AST Application Requirements
- NOVA, VSA or VWE 3-phase reclosers
- Form 6 controls
- Source- and load-side Potential Transformer (PT) for control power
Communication Options
- Single or multi-mode fiber optics (Serial or Ethernet)
- RS-232/RS-485
Radio Options
- Preferred MDS and Ethernet radios
