In a society where technology is continuously improving, expectations of reliability are also increasing. As such, the expectations for the reliability of electric power distribution are increasing. Given power outages or full-scale utility failures, people want to feel secure and able to continue their daily schedules.
The choice of power system distribution topology is critical to prepare for outages. Five most common critical power distribution topologies for a mission-critical industry include: Secondary-Selective ‘Main-Tie-Main’ Arrangement, Main-Tie-Main topology, Ring Bus Arrangement, Primary Loop Arrangement, and Composite Primary Loop/Secondary Selective Arrangement.
