Electrical functional testing is very important and critical part of any electrical project. Most of the times it is necessary to hire a third party in order to conduct the function testing of electrical systems. Big electromechanical companies are having their own testing and commissioning teams that can perform the electrical tests dpending upon the… Read More »
Being an electrical engineer on a construction project is a very tedious and responsible job. Electrical site engineer is wholly responsible for the ordering of materials as per the pre approved material submittals and an electrical project specifications. Here in this article we have included the complete list of testing requirements for an electrical system… Read More »
What is Magnetism? Magnetism is the study of magnetic fields and their effect on materials. The effect is due to unbalanced spin of electrons in atom. It is readily observed every day from the simple magnet that attracts nails and other metals to cassette tapes to magnet-driven trains. In terms of applications, magnetism is one of… Read More »
In a paramagnetic material the magnetization of the material is (approximately) directly proportional to an applied magnetic field. However, if the material is heated, this proportionality is reduced; for a fixed value of the field, the magnetization is (approximately) inversely proportional to temperature. This fact is encapsulated by Curie’s law: where is the resulting magnetisation… Read More »
To best understand the Electromagnetic Induction lets first have a look on two important laws relating to the subject of this article. Lenz’s law is named after a Russian physicist of Baltic German descent Heinrich Lenz in 1834, and it states that, if an induced current flows, its direction is always such that it will… Read More »
There are many different tests for the transformers depending upon the usage, type and size but most common tests are: Short Circuit Test Open Circuit Test Let us first understand that what does short circuit and open circuit means in electrical transformers: What is a Short Circuit? A short circuit is an electrical circuit that… Read More »
