About the Project
A bank office building in a dense business district such as Maslak carries IT rooms, operations floors and heavy HVAC loads at the same time, and much of it must keep running without interruption. Istanbul’s 34.5 kV distribution network is generally dependable, yet short voltage dips and planned outages can still disrupt financial operations. The electrical infrastructure therefore has to keep faults local and transfer critical loads to a standby source within seconds, while remaining easy to maintain during business hours.
For an office building of this scale, the typical answer is a split main distribution board fed by two transformers and separated by a bus coupler. Each busbar section is rated around 2,500 A, while a generator of approximately 1,000 kVA carries emergency and critical loads. Floor distribution boards take power up the riser to each level, power factor correction panels balance the reactive power and harmonics created by HVAC drives and IT equipment, and lighting panels work alongside the building automation system.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers the complete low-voltage distribution, from the transformer outgoers to the floor boards and lighting circuits.
- Main distribution board (DevPanel): 2 × 2,500 A split busbar with coupler, 65 kA / 1 s, Form 3b – Form 4a, generator transfer scheme.
- Floor distribution boards (DevBox): Separate outgoing groups for office, IT and mechanical loads on every floor.
- Power factor correction panels (DevComp): Detuned, stepped reactive power compensation.
- Lighting panels (DevPower): General and emergency lighting, controlled through the building automation system.
- Testing and commissioning: Design verification to IEC 61439-1 / -2 and site testing.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Dual transformers and coupler
Two transformers feed separate busbar sections; if one is out of service the coupler closes and priority loads move to the remaining transformer.
IT continuity
Server and network rooms are supplied through UPS systems, which bridge the gap until the generator picks up the load.
Harmonic management
Drives, LED lighting and IT loads generate harmonics; detuned compensation protects both power factor and voltage quality.
Energy monitoring
Meters in the main and floor boards let the building management system track consumption by system and by tenant area.
Frequently Asked Questions
What is the installed power for Kuveyt Türk Maslak Office?
For an office building 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 rated 2 × 2,500 A, the medium voltage is 34.5 kV and the standby generator is around 1 × 1,000 kVA.
Why is Form 3b – Form 4a separation used in office buildings?
Internal separation allows one outgoing circuit to be worked on while the others stay energised, so maintenance can be carried out safely while the office floors remain in use.
Which loads does the generator supply?
Typically IT, security, fire safety, lifts and emergency lighting take priority, while comfort loads are reconnected in stages according to the available generator capacity.
