The purpose of this blog is to share my experience and learning with others in the industry. I hope some of this information may be useful to someone out there who is trying to find out some technical information through a web search.

This blog is trying to give few technical information regarding distribution system design, with particular reference to Buildings. The information contained herein is generally based on practices followed as per British Standards(BS), IET Regulations 16th Edition and Indian Standards.

Electrical services for a building generally includes the following activities:

Usually, the design of a building starts with the load estimation, and then proceeds to equipment selection, lighting design, deciding small power/power socket outlet positions, mark up of plans for drafting etc.

1. Load estimation and Load calculations

2. Transformer sizing calculations

3. Circuits

4. Distribution planning

5. Choosing protective devices
6. Selection of cables, cable sizing calculations
7. Cable trunking and Tray sizing
8. Lighting design
9. Emergency lighting
10. Standby systems- Diesel Generator
11. Standby systems- UPS
12. Power factor compensation
13. Lightning protection
14. Earthing systems

Most of the design activities  outlined above can be done by manual hand calculations. It is better to use a software package for accurate design of Lighting.

In the following pages I am trying to give few details about each of these.


Some useful packages would be
·        DiaLux,
·        ReLux,
·        Visual Lighting software etc..

For power calculations
·        AMTECH
·        HEVACOMP
·        ECODIAL
·        SIMARIS
are popular software available.
