Electrical Low Voltage System Distribution Design

This course is dedicated to students looking to acquire electrical low-voltage power design experience from scratch.

This course covers low voltage distribution system design-related topics for a total duration of 10 hours.

Essentially, the course begins section 1 by introducing the well-known drawing software "AutoCAD" and emphasizing its different toolbar options to prepare the student to be familiar with its use. Consequently, lighting design and lux calculations using DIALux software are fully explained in section 2 to prepare the lighting distribution system that will be explained and designed as a following step in section 3.

After that, lighting & power systems distribution are covered in sections 3 & 4, which in turn prepares the student to understand how to gather information and calculate the total connected loads following the lighting and power designed layouts to be reflected in the panel schedules and single line diagrams which will be explained in the 5th section of this course.

Once reaching this stage of the course, you will have to perform a range of low voltage system-related calculations of sizing Transformers, Generators, Cables, Circuit Breakers, calculations of voltage drop and short circuit current levels & power factor correction to ensure a safe design for the entire system for the aim of reflecting the calculated values in the single line diagram of the project. All these calculations will be explained separately in detail using simple steps that you can apply manually and with the help of predefined Excel sheets for solving different formulas in section 6.

The last section of this course covers the earthing & lightning system topics, emphasizing their different types, components & the appropriate methods to design these systems following international standards.

Furthermore, design topics in this course are explained by exploring pictures of different electrical equipment installed on the site to clarify the bond between the design and real site installations.

Besides, the course is enhanced with a variety of helpful resources that are attached to it.

In a nutshell, the sections of this course are arranged in ascending relevant stages, starting from section 1, which introduces AutoCAD, and finalizing the course by explaining the earthing & lightning systems which could be designed in the last stages of the design.
