Automatic Source Transfer (AST) solution

Eaton's Automatic Source Transfer (AST) solutions, also known as Automatic Transfer System (ATS) 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 utilities dramatically minimize service disruptions and quickly re-energizes critical customers. The AST solution is available for three-phase and triple-single devices.

Expanded capability
Premium critical load service

Spesifikasi

Key functions of the AST

HIGH-SPEED, PEER-TO-PEER PROTOCOL

Enables transfer to an alternate source in as little as six cycles ensuring minimal service disruption

PeerComm protocol enables the two reclosers to maintain constant communication

FLEXIBLE, USER-SELECTABLE RESTORATION OPTIONS

Helps utilties quickly return systems back to the normal states 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 retoration to occur once the preferred feeder voltage returns

MINIMIZED 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 backup power is required, including generators
