Power Transmission

High Voltage Substations

  • Electric Expertise Group
  • Activities of this group starts from basic electrical design of power substations, comprising single line diagram, grounding system, protection and control schemes and can be extended to the more sophisticated design of schematic diagrams and communication systems. Design of Low Voltage and High Voltage systems, determining technical specification of power and auxiliary transformers and HVAC plus lighting of control rooms and switch yards are performed in this group. Keen cooperation with other technical groups will guarantee the maximum design suitability and safety for power substations.


  • Civil Expertise Group
  • Architectural and structural Design of control rooms and all other auxiliary buildings of a power substation are performed in this expertise group. Cable galleries, switchyard foundations, and access road design are also part of activities in this group. Design of drainage system of substations and courtyard planning are also done by experienced experts of civil group. Close cooperation with other technical groups secures the perfect design work of this section.

  • Project Control Group
  • Main task of Project Control Group is to assure the project managers of proper time consumption in every individual activity of their project. For this sake from the very beginning of project all activities and their most likely time required are discussed and agreed between the project manager and this group. Upon commencement of project and in each agreed period of time a report of work progress will be prepared and handed over to the project beneficiaries. In this report along with the time, the resources used for each activity and required/remaining resources would be notified for the resource assignment in future. All standard project control softwares are available and may be used upon the requirements of project.


  • Projects Executive Groups
