About the Project
On a university campus, power is distributed across many buildings with very different usage profiles: lecture halls busy during the day, laboratories drawing steady load around the clock, residences used in the evenings and at night, plus sports and social facilities. Kaliningrad’s damp, cool Baltic climate increases the risk of condensation in plant rooms and extends the heating season. For a campus of this scale the installed power is typically around 6,400 kVA. The distribution system must share load evenly between buildings and prevent a fault in one building from affecting the others.
In the typical solution, four 1,600 kVA transformers fed from the 10 kV distribution connect to a 2 × 3,200 A main board split by a bus coupler, and each building is supplied radially from it. Every building has its own distribution board, and selective protection confines a fault to the affected building or floor. A 2 × 1,250 kVA generator capacity backs up critical laboratory equipment, life-safety systems and emergency lighting. Form 4a – Form 4b construction and IP31 – IP41 enclosures support safe, long-life operation in a humid environment.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers the low-voltage system from the campus main distribution to building and floor boards.
- Main distribution boards (DevPanel): 2 × 3,200 A, 65 kA / 1 s, dual section with bus coupler and building feeders.
- Building and floor boards (DevBox): Sub-distribution for teaching, laboratory, residential and administrative buildings.
- Power factor correction (DevComp): Automatic stepped compensation that follows the varying campus load.
- Lighting and power panels (DevPower): Auditorium, corridor, outdoor and emergency lighting circuits.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Radial multi-building distribution
Each building has its own feeder from the main board, so maintenance or a fault affects only that building.
Diverse usage profiles
Lecture, residence and laboratory loads peak at different times, allowing transformer capacity to be used more efficiently.
Humidity and condensation
Anti-condensation heaters and suitable IP ratings prevent moisture problems, especially in basement plant rooms.
Laboratory supplies
Laboratory equipment that must run continuously is fed from separate, generator-backed circuits.
Frequently Asked Questions
What is the installed power for a campus like Immanuel Kant Campus?
For a university campus of this scale the installed power is approximately 6,400 kVA, with a typical transformer configuration of 4 × 1,600 kVA. The main busbar is typically 2 × 3,200 A with a 65 kA / 1 s rating, supplied at 10 kV medium voltage.
How is selectivity achieved between campus buildings?
Building feeder breakers in the main board and protective devices in each building board are coordinated in time and current, so a fault opens only the breaker nearest to it.
How are switchboards protected in a humid climate?
Suitable IP ratings, thermostatically controlled panel heaters and ventilated plant rooms limit the effect of condensation on insulation and contacts.
