Decryption of the abbreviation "Computer" and the list is included in this section of the documentation

1. Specifications (THAT), received from the organization, which will provide electricity to the facility.
2. Floor plans and requirements for power supply, received from the developers of related sections of the project.
3. Terms of reference (TZ) for the development of the object.

After receiving the initial data, the actual design process begins. Thus at first the category of reliability of system of power supply is defined and all information on loading from consumers gathers. After that, the structure of the power supply system of the facility is determined and the basic schemes of electrical networks of all facilities and switchgear are developed.. in addition, measures must be taken,which exclude electric shock. Developed documentation and is the main content of the PC section.
