The Ministry of Health Building in Georgia is a public building in Tbilisi housing administrative offices, meeting rooms and IT infrastructure. Devpan supplied the main distribution, sub-distribution, power factor correction and lighting boards.

About the Project
Ministry buildings combine intensive daytime office use with functions that cannot tolerate interruptions: server rooms, archives, call and coordination units. For an institution that coordinates health-sector responses, continuity of supply is part of service continuity rather than a matter of comfort. Tbilisi’s warm summers and cold winters also keep the HVAC load significant throughout the year.
For a public building of this scale, a typical arrangement is a 2 × 1,250 A main distribution board fed by two 800 kVA transformers and split by a bus coupler. If one transformer is out of service, priority loads can be transferred to the other through the coupler. A 630 kVA generator protects IT, security and emergency lighting loads; DevBox boards serve the floors, DevPower panels manage lighting and DevComp corrects the power factor.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers low-voltage distribution from the transformer outgoing ways to floor boards and IT supplies.
- Main distribution board (DevPanel): 2 × 1,250 A, 50 kA / 1 s, Form 3b, with bus coupler and generator changeover.
- Sub-distribution boards (DevBox): office floors, meeting rooms, archives and server rooms.
- Power factor correction (DevComp): automatic reactive compensation for office and HVAC loads.
- Lighting and power panels (DevPower): interior, façade and emergency lighting circuits.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Dual-transformer redundancy
Two transformers operate with a bus coupler, so critical loads stay supplied while one unit is under maintenance.
IT continuity
Server rooms are fed from a generator-backed section through dedicated, selectively protected feeders to their UPS inputs.
Energy monitoring
Metering by floor and system supports energy efficiency reporting in public buildings.
Meeting room loads
Audio-visual and HVAC systems are fed by separate circuits for each meeting room.
Frequently Asked Questions
What is the installed power for the Ministry of Health Building in Georgia?
For a public building of this scale the installed power is approximately 1,600 kVA, with a typical transformer configuration of 2 × 800 kVA. The main busbar is planned at 2 × 1,250 A with 50 kA / 1 s withstand, on a 10 kV MV supply and with a 1 × 630 kVA standby generator.
Why two transformers instead of one larger unit?
A two-transformer arrangement prevents a complete loss of supply during maintenance or a fault and keeps priority loads running through the bus coupler.
Why is Form 3b separation suitable for this building?
Form 3b separates functional units from the busbars and from each other, striking a good balance between safe maintenance and compact board dimensions in a medium-sized public building.
