About the Project
Mid-sized healthcare buildings usually have limited plant space, yet their diagnostic, treatment and support services expect the same continuity as a large hospital. Moscow’s winters hold heating and ventilation loads high for months, and with a single-generator backup scheme it must be planned carefully which loads return, and when. For a facility of this scale the installed power is typically around 3,200 kVA. The distribution architecture is expected to be compact, easy to maintain and well suited to load prioritisation.
In the typical solution, two 1,600 kVA transformers fed from the 10 kV network supply a 2 × 2,500 A main board split by a bus coupler. Each transformer is sized so that it can carry the priority loads alone if the other is out of service. A 1 × 1,000 kVA generator takes over only critical consumers, using load shedding and staged load acceptance. Form 3b – Form 4a segregation strikes a balance between safe maintenance and footprint in a compact switchroom.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers the facility’s low-voltage distribution from the transformer outputs to the service boards.
- Main distribution boards (DevPanel): 2 × 2,500 A, 65 kA / 1 s, two sections with bus coupler and generator changeover.
- Motor control panels (DevControl): Starter and drive feeders for ventilation, cooling and pump motors.
- Sub-distribution boards (DevBox): Floor-by-floor distribution for examination, treatment and support areas.
- Power factor correction (DevComp): Automatic stepped, detuned reactive power control.
- Lighting and power panels (DevPower): Lighting and small power circuits for clinical and support spaces.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Load management on one generator
While the 1 × 1,000 kVA generator is running, non-critical feeders are shed automatically and priority loads are reconnected in stages.
Transformer redundancy
Each transformer is selected to carry the priority loads alone during maintenance of the other, with the bus coupler closing the gap.
Compact switchroom
Form 3b – Form 4a construction balances safe access against switchboard footprint where plant space is tight.
Emergency lighting continuity
Escape routes and treatment areas keep their lighting through generator and battery-backed systems.
Frequently Asked Questions
What is the installed power for a facility like the Skolkovo ORK Project?
For a healthcare facility of this scale the installed power is approximately 3,200 kVA, with a typical transformer configuration of 2 × 1,600 kVA. The main busbar is typically 2 × 2,500 A with a 65 kA / 1 s rating, supplied at 10 kV medium voltage.
Is a single generator sufficient?
A typical 1 × 1,000 kVA generator is planned to supply critical consumers rather than the whole load; load-shedding logic keeps it within its rating.
How do you choose between Form 3b and Form 4a?
Form 4a is used on critical outgoing units to separate terminals as well; for less critical groups Form 3b provides adequate safety with a smaller footprint and cost.
