Electrical engineering and consultancy since 2009.
EPROSİS Elektrik Mühendislik Müşavirlik Yapı Sanayi ve Ticaret Ltd. Şti. has provided electrical engineering and consultancy services in Ankara since 2009.
Our office designs the electrical systems of public and industrial facilities, wastewater treatment plants in particular. We run the whole process in-house, from the load list to the single-line diagram, panel and control schematics, cable schedules and calculation reports.
We work from each plant's energy demand and operating conditions. The aim is a system that is reliable, efficient and easy to maintain.

A project moves through five steps.
The output of each step is the input of the next, which is why we keep the whole process in-house.
- 1
Load list
Every consumer in the plant is listed with its rating and duty. The energy demand follows from here.
- 2
Single-line diagram
Supply, transformer, busbars and feeders are defined in one diagram.
- 3
Panel and control schematics
Power and control circuits are drawn for each panel, together with the terminal lists.
- 4
Cable schedules
Cable types, cross-sections and routes are entered into the schedules.
- 5
Calculation reports
Cable sizing and voltage drop, transformer and generator rating, earthing and lightning protection calculations are reported.
