About the Project

About the Project

In a villa complex used for official hospitality, the electrical infrastructure is expected to work invisibly and without fail. The villas are spread across extensive landscaped grounds, each with its own air conditioning, kitchen, pool, heating, security and communication systems. Supplying these loads over long cable routes calls for careful planning of voltage drop and selectivity. Security systems, perimeter lighting and communications must remain available even during a utility outage, and generator and switch rooms are expected to be quiet, orderly and easy to maintain.

For a villa complex of this scale, the typical arrangement is roughly 2 × 800 kVA of transformer capacity supplied at 10 – 34.5 kV depending on the local network, with a coupled main LV board. DevPanel boards with 2 × 1,250 A busbars, 50 kA / 1 s withstand and Form 3b segregation distribute separate, selectively protected radial feeders to each villa. Inside the villas, DevBox boards provide orderly distribution for living areas, plant rooms and pool equipment. DevPower panels manage landscape and perimeter lighting through scenes, DevComp corrects the reactive load, and a generator of approximately 630 kVA backs up security and critical loads.

Scope

Devpan Scope and Switchboard Architecture

Devpan’s scope runs from the complex’s main LV distribution to the villa boards and landscape lighting.

  • Main distribution boards (DevPanel): 2 × 1,250 A busbars, 50 kA / 1 s, Form 3b, bus coupler and generator transfer section.
  • Villa boards (DevBox): IP31 – IP41 sub-distribution boards for living areas, kitchens, pools and plant rooms.
  • Landscape and perimeter lighting (DevPower): Scene-controlled boards for road, garden, façade and perimeter security lighting.
  • Power factor correction (DevComp): Stepped automatic compensation for HVAC and pool pump loads.

Project-Specific Engineering Topics

Radial villa supply

Each villa is fed by its own feeder from the main board, so a fault or maintenance in one villa does not affect the others.

Continuity of security loads

Security, CCTV, access control and perimeter lighting are fed from a separate priority busbar backed by UPS.

Long cable routes

Feeders running across the grounds are sized for voltage drop and for reliable short-circuit protection at the far end.

Pools and wet areas

Pool equipment and wet-area circuits are protected by high-sensitivity RCDs and housed in enclosures with suitable IP ratings.

FAQ

Frequently Asked Questions

What is the installed power of the Presidential Villas?

For a villa complex of this scale, the installed power is approximately 1,600 kVA with a typical transformer configuration of 2 × 800 kVA. The main busbar is typically rated 2 × 1,250 A with 50 kA / 1 s withstand; the medium voltage is 10 – 34.5 kV depending on the local network, and standby comes from a generator of around 1 × 630 kVA.

Why is radial distribution preferred in villa complexes?

With radial distribution each villa has an independent feeder, which limits the impact of faults and maintenance to a single villa and allows consumption to be monitored villa by villa.

How is landscape lighting controlled?

DevPower panels manage road, garden and façade lighting in groups using astronomical clocks, photocells and scene control, while security lighting runs on separate circuits.
