Lighting calculation is required to achieve a good lighting design and to determine the number of lighting fixtures required for each room/part in your building. Lighting calculation can be done either manual way or using the software.

This post will focus on designing using DIAlux software, I’m using DIAlux 4.13…

This is a short article to describe how to create faceplates within a popup screen in TIA portal 15.1. The faceplate is a feature used to create an individually configured display for certain objects/components within your system to show more details/information related to it. You can use faceplates several times…

In this article, we will discuss how to prepare DB loading schedule, and the branch circuit load calculations related to it including, total connected loads. loads unbalance %, total demand loads, demand factors, and max. demand loads.

The distribution board is part of the distribution system, which distributes electrical power…

Protective Device Coordination — ETAP

Protective devices such as fuses and circuit breakers are playing a big rule in power system protection. When a fault occurs on the electrical system short-circuit/overloading the fault current must be interrupted quickly.

Coordination study is required to coordinate upstream with downstream branches to minimize interruption of electrical power in…

Harmonic Analysis using ETAP

Harmonic is one of the most important concepts on the power system that cannot be neglected since it can affect the power quality and operation of equipment. High levels of Harmonics in the system may lead to overheating component thus causing shorten the life of the…

Motors are a widely used industry to produce a mechanical power to run ‎various applications such as compressors, pumps, fans, etc. Naturally, motors draw a huge amount of current when it powered-on/energize, under starting condition, high inrush current is flow which can reach up to six times the rated current…

ETAP has been one of the most popular software used by many companies and electric utilities worldwide to perform complex electrical systems analysis/studies on different projects.
Before starting to perform any analysis with ETAP it so important to have a good background in all technical aspects in power systems, electrical…
