List of Functional Tests Required for Electrical Systems

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 depending upon the… Read More »

Electrical Testing Requirements for an Electrical Project

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 »

Introduction To Induction & AC Electric Motor | Working Principle & Types

An induction motor is an AC electric motor in which the electric current in the rotor of electric motor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. One of the most common electrical motor used in most applications is known as Induction Motor. Most commonly used motors… Read More »

Faraday’s Law of Electromagnetic Induction

FARADAY’S LAW OF ELECTROMAGNETIC INDUCTION According to the Faraday’s law of electromagnetic induction, emf gets induced in the rotor. As the rotor circuit is closed one so, the current starts flowing in the rotor. This currents called the rotor current. This rotor current produces its own flux called rotor flux. Since this flux is produced… Read More »

Explanation of Hysteresis Loss & Eddy Current Losses in Transformers

Transformer is very simple and basic part of electrical system and considered most efficient of electrical components of machines. If we consider experimental models which are using superconducting windings then we may talk about achieving the the performance of 99.75 percent as well. In practice, energy is found to be lost in the windings, core and… Read More »

Electric DC Motors Principle Of Operation & Types

First of all we should understand the concept of electric DC motors, an electric motor is a machine that converts electrical energy into mechanical energy. Most of the electric motors operate through the interaction between electric motor’s magnetic field and winding currents to generate force within the motor. In certain applications, such as in the… Read More »
