 What's included?

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

In fact, this course covers low voltage distribution system design-related topics in a total duration of 10 hours.

Essentially, the course begins Section 1 with introducing the well-known drawing software "AutoCAD", by emphasizing on its different toolbar options for the purpose of preparing the student to be familiar with its use.

Consequently, lighting design and lux calculations using DIALux software is fully explained in Section 2 for the aim of preparation for the lighting distribution system that will be explained and designed as a following step in Section 3.

Thereafter, lighting & power systems distribution are covered in Sections 3 & 4, which in turn prepares the student understand how to gather information and calculate the total connected loads in accordance with 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 and 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 details using simple steps that you will be able to 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 and lightning system topics emphasizing on their different types, components and the appropriate methods to design these systems in accordance with the international standards.

Furthermore, design topics in this course are explained in accordance with explored pictures of different electrical equipment that are installed in the site for the purpose of clarifying the bond between the design and real site installations.

Besides, the course is enhanced with a variety of helpful resources that are attached with it (XLSX, DOC, DWG, and PDF)
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.
