Substation Design

Substation Design addresses a wide range of substation design criteria: breaker arrangement, equipment selection, substation performance and availability, substation physical layout, environmental impacts, etc. Successful substation design puts priority on reliability, operability, maintenance, standardization, safety, and environmental impacts.
