What is Electricity? Electricity is a form of energy that can be easily changed to other forms. Electricity comes mainly from 2 sources i.e. Power stations and generators that supply a lot of electricity and normally used in many electrical appliances and industrial applications. From Electric Cells or batteries which are used for portable purposes. To… Read More »
Single Phase power circuits Single phase electric power or circuit refers to the distribution of alternating current electric power using a system in which all the voltages of the supply vary in corresponding exactly. Single-phase distribution is used when loads are mostly used for the purpose of lighting and heating which can also be for… Read More »
What is a Diode? Di+Ode is a semiconductor device with two terminals allowing the flow of current in one direction only, diodes are made up of Silicon, Germanium & GaAs. The perfect diode would be a perfect conductor in one direction (forward bias) and a perfect insulator in the other direction (reverse bias). In many situations, using… Read More »
What is the Wheatstone Bridge? The Wheatstone Bridge consists of a dc voltage source, four resistors and a detector. The detector is a type of ammeter called a galvanometer. The galvanometer is used to detect the condition ig = 0 .When the circuit satisfies this condition we say that “the bridge is balanced”. A Wheatstone bridge… Read More »
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 »
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 »
