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 »
What is Windmill or Wind Power Turbine? Windmill or wind turbines are very simple devices which are used to generate wind electricity by using the wind power. The principle of wind mill is very simple i.e. convert the wind’s kinetic energy into mechanical energy which further converts the mechanical energy to electricity so the overall… 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 »
