This Practice describes minimum requirements for design, performance, inspection, testing, and documentation of automatic delayed transfer systems (ATS) for two-source secondary selective substations, typically known as Main-Tie-Main transfer scheme. ATS provides automatic restoration of bus voltage upon loss of one of the sources. This Practice also covers remote monitoring and control requirements. This Practice does not cover fast bus transfer or delayed in-phase transfer systems.
