Within Europe the European Committee for Electrotechnical Standardization (CENELEC) has standardised the both the designation and colour of cables. ...
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
The International System of Units (abbreviated SI) is the world's most widely used system of units. The system consists of a set of units and prefixes...
A single phase system is perhaps the most common type of system most people are familiar with. This is what people have in their homes and what appliances...
