About the Project
In a manufacturing plant the electrical system sets the pace of the production line. Presses, welding equipment, machine tools, compressors and ventilation motors produce high starting currents and fluctuating load profiles; variable speed drives add harmonics, and dust, oil mist and vibration on the shop floor create a demanding environment for switchgear. An unplanned stoppage leads to scrapped work in progress and lengthy restart times, so the distribution must be robust and maintainable.
For a factory of this scale the typical architecture is a split main distribution board rated 2 × 4,000 A with 80 kA / 1 s short-circuit withstand, fed by two transformers of about 2,500 kVA each. Form 4b separation and IP54 protection allow a single outgoer to be worked on safely while production continues. Motor control centres are grouped by line, compensation panels supply reactive power locally, and generators of approximately 2 × 1,250 kVA provide enough backup to keep or safely shut down critical processes.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers the plant’s low-voltage distribution and motor control infrastructure, from the transformer outgoers to the machine feeders.
- Motor control centres (DevControl): Withdrawable starter and drive feeders for production lines, compressors and fans, IP54.
- Main distribution board (DevPanel): 2 × 4,000 A split busbar with coupler, 80 kA / 1 s, Form 4b, generator transfer.
- Power factor correction panels (DevComp): Detuned compensation with a high number of steps.
- Sub-distribution boards (DevBox): Distribution for machine groups, workshops and auxiliary buildings.
- Lighting panels (DevPower): Production hall, storage and emergency lighting circuits.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Motor starting currents
Large motors are started with soft starters or drives to prevent voltage dips and stress on the busbar.
Withdrawable MCC design
A faulty feeder can be withdrawn and replaced with a spare while the rest of the line keeps running, cutting downtime to minutes.
Dust and oil environment
IP54 enclosures, filtered ventilation and gasketed doors protect internal components from the shop-floor atmosphere.
Local compensation
Detuned compensation for drive and motor loads keeps the power factor high and avoids reactive energy penalties.
Frequently Asked Questions
What is the installed power for Portakal Engineering Factory?
For a manufacturing plant of this scale the installed power is approximately 5,000 kVA, with a typical transformer configuration of 2 × 2,500 kVA. The main busbar is typically rated 2 × 4,000 A with 80 kA / 1 s withstand, the medium voltage is 34.5 kV and generator capacity is around 2 × 1,250 kVA.
Why is Form 4b preferred in factories?
In Form 4b the terminals of each outgoer are also separated, so work on one machine feeder can be done while neighbouring circuits stay live and production continues.
How are MCCs connected to production automation?
Starters and drives are linked to the control system over an industrial network, so status, current and fault data are visible on operator screens.
