A SOURCE CHANGE OVER SYSTEM HAVING DISTRIBUTED ELECTRICAL INTERLOCKING

摘要

The present invention discloses a source change over system having distributed electrical interlocking. The source change over system includes an automatic transfer switch (ATS) for issuing control commands, multiple switch disconnectors communicatively coupled with the automatic transfer switch for tripping actuators for break operation based on the control commands, plurality of Human Machine Interfaces (HMIs), field bus communication interfaces and input output interfaces connected with each of the switch disconnectors. The switch disconnectors are interconnected by one or more communication channels and are embedded with the electrical interlock intelligence with a token exchange method.
