About the Project
In a building that combines studio and office functions, power quality matters as much as continuity. Editing, audio and video processing equipment is sensitive to voltage fluctuation and harmonic distortion, while studio lighting creates large load swings in a short time. In Maslak’s high-density business environment, energy taken from the 34.5 kV network must reach sensitive loads clean and stable, and the earthing arrangement has to be designed to avoid noise.
For a building of this scale, a typical approach is to use a main distribution board of about 2 × 2,500 A, fed by two transformers, and to separate sensitive and mechanical loads onto different busbar sections. This keeps distortion from HVAC drives away from studio equipment. Floor boards supply office and technical areas through dedicated outgoers, detuned compensation limits harmonics, and a generator of approximately 1,000 kVA secures critical studio and IT loads.
Devpan Scope and Switchboard Architecture
Devpan designed and built the building’s low-voltage distribution, from the main board down to the floor and lighting panels.
- Main distribution board (DevPanel): 2 × 2,500 A busbar with coupler, 65 kA / 1 s, Form 3b – Form 4a, separate sections for sensitive and mechanical loads.
- Floor and technical boards (DevBox): Dedicated feeder groups for office, studio and server areas.
- Power factor correction panels (DevComp): Detuned, fast-stepping reactive power compensation.
- Lighting panels (DevPower): Office, common area and emergency lighting circuits.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Clean power segregation
Studio and IT loads are fed from busbar sections separate from HVAC and lift loads, reducing harmonic interaction.
Earthing arrangement
A TN-S system with a separate protective conductor prevents ground loops that could introduce noise into audio and video equipment.
Rapid load changes
Fast-stepping compensation responds to the sudden load changes caused when studio lighting is switched on and off.
Selective protection
Discrimination between floor and main board breakers ensures a fault in one area does not affect the whole building.
Frequently Asked Questions
What is the installed power for Walt Disney Studio Maslak?
For an office and studio 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 generator is around 1 × 1,000 kVA.
How is studio equipment protected from harmonics?
Sensitive loads are supplied from separate busbar sections, and detuned compensation, with active filtering where needed, keeps voltage distortion low.
What does internal separation provide during maintenance?
With Form 3b – Form 4a separation, one outgoing circuit can be worked on while the others remain live, so studio and office activities continue.
