Large Transformer Installation for a Metallurgical Site
Challenge
The customer was expanding production capacity and required a new power node without a prolonged shutdown of active lines. Existing infrastructure was already close to peak utilization, so switching errors could trigger expensive downtime.
Solution
DOWBUSH energo performed staged network audit, refined load assumptions, and prepared a migration scenario that avoided simultaneous outage of critical segments. Installation, switching updates, and commissioning were executed during low-load windows.
Results
After completion, the site gained stable reserve capacity for new lines, while forced shutdown events in the first operating quarter were reduced by 58%. Exposure to schedule penalties also declined.
Technical details
The solution included a new 10/0.4 kV transformer node, updated protection logic, selectivity validation, and integration with plant dispatch monitoring.
Client quote
“Meeting schedule without stopping the plant was critical. Delivery was precise and technically disciplined.”
