How Is a Transformer Fitted Into a Substation?
Quick answer — Substation design places the transformer(s) with the correct clearances, fire-protection (walls/containment), foundations, earthing, busbar and cable connections, protection, metering and ventilation, and considers the fault level, noise, oil containment and future expansion. The transformer and the substation are designed together so the rating, voltage and protection are coordinated.
What is involved in substation transformer design?
Layout and clearances
The transformer is placed to meet the electrical clearances, the site constraints, the access for maintenance, the fire separation and the future expansion.
Connections and protection
The busbar/cable, the bushing and the connection, the protection and the metering are designed, and the fault level and voltage regulation checked.
Ancillaries
Oil containment and fire protection, earthing, cooling, ventilation and the control/protection panel are provided as part of the substation.
