About the Project
In Sudan the grid supply can be subject to frequent voltage fluctuations and unplanned outages, so in a consulate building the generator should often be treated as a second source in regular use rather than a rarely used backup. Very high summer temperatures increase cooling loads, while fine dust and sandstorms put pressure on board ventilation and component life. Uninterrupted operation of security, communication and consular service systems sits at the centre of the design.
For a consulate building of this scale the typical solution is a main distribution board rated 1,600 A, fed by a single transformer of about 1,000 kVA and a generator of approximately 500 kVA. An automatic transfer scheme and voltage monitoring relays manage source changeovers, and priority loads are grouped in a separate section so generator capacity is used efficiently. Sub-distribution boards feed office and security areas separately, and compensation and lighting panels complete the system.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers the building’s low-voltage system, from main distribution to sub-boards and security lighting.
- Main distribution board (DevPanel): 1,600 A, 50 kA / 1 s, Form 2b – Form 3b, automatic mains-generator transfer and voltage monitoring.
- Sub-distribution boards (DevBox): Separate distribution for office, consular service and security areas.
- Power factor correction panels (DevComp): Stepped compensation with control suited to generator operation.
- Lighting panels (DevPower): Interior, perimeter security and emergency lighting circuits.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Unstable grid
Voltage monitoring relays detect over- and under-voltage, protect sensitive loads and initiate transfer to the generator when needed.
Dust and sand
Filtered ventilation and gasketed doors limit fine dust ingress into the boards and extend maintenance intervals.
Generator-compatible compensation
Capacitor steps are switched out in a controlled way during generator operation to avoid over-compensation.
Security system supply
Access control, CCTV and communication systems are fed from separate UPS- and generator-backed circuits.
Frequently Asked Questions
What is the installed power for the Consulate of the Netherlands, Sudan?
For a consulate building of this scale the installed power is approximately 1,000 kVA, with a typical transformer configuration of 1 × 1,000 kVA. The main busbar is typically rated 1 × 1,600 A, the medium voltage is 11 kV and the generator is around 1 × 500 kVA.
Can the generator supply the whole building?
The generator is usually sized below the transformer rating; priority loads are grouped in a separate section and secondary loads are reconnected in stages according to available capacity.
What matters in switchboard design for a hot climate?
Device ratings are derated for high ambient temperature, the electrical room is air-conditioned and the internal temperature rise of the boards is verified by calculation.
