During the design of an electrical installation for a building, spaces that are required as electrical rooms need to be provided for very early in the planning and design process. I will try to present this in a form of a few basic concepts so that non-electrical readers can benefit from it. There are also a few diagrams at the end of this post, but I do want to go too technical here as this may turn off the non-electrical readers. Kbc 5 Game For Pc here. If you need a more technical discussion, I will send a few posts of electrical substation layout and design in future. ================= RELATED ARTICLES: About the author: ================= Sources of electrical supply Two (or sometimes three) sources of electricity are normally required in high-rise buildings: 1) The normal mains supply from the electric supply authority or the local electricity supply company in some countries. 2) The standby or emergency supply for the standby electric generators.

In most situations, this supply is not an option, but a mandatory requirement for buildings that exceed a certain size. 3) The uninterruptible power supplies, or commonly called UPS. This is only needed in certain types of office buildings and in some hospital buildings. Voltage level of the incoming supply The normal mains supply taken from the authority may be taken at HV (high voltage, normally 11 kV in this country), or LV (low voltage, 415 Volt, three-phase four-wire).

Whether it is the LV or HV supply depends on the size of the maximum electrical demand to be expected of the planned building when it is in full operation. It also depends on the effects of voltage drops and the level of voltages that are currently available from the supply authority.
