Define the generation topology
Switchgear in a generation system may connect generators, transformers, utility sources, buses, feeders, and auxiliary loads. The correct application depends on operating modes, transfer or paralleling philosophy, fault duty, and protection interfaces.
Inputs to collect
| Input | Why it matters |
|---|---|
| Generator and transformer schedule | Establishes source ratings and interfaces |
| Bus and feeder arrangement | Defines normal, standby, and maintenance paths |
| Operating modes | Clarifies transfer, synchronizing, and isolation boundaries |
| Fault and protection study | Coordinates breakers, relays, CTs, and trips |
| Metering and control | Defines local, remote, and plant-system signals |
| Environment and access | Affects enclosure, cooling, cable entry, and service |
Scope boundary
This article organizes application inputs; it does not approve generator paralleling, protection settings, or a system one-line. The power-system engineer must verify the complete design.
