We discuss various types of electric motors, induction motors, including DC motors, synchronous motors, and other special types of motors. We explain the working principles, features, uses, and testing of electronic motors. This section is a collection of knowledge about all things related to electric motors.
We discuss all things about transformers – from basic theory to modern progress. Learn about all the different types of transformers – two winding transformers, autotransformers, power, and distribution transformers, single-phase and three-phase transformers – and more.
We discuss various types of electronic and electrical measurements. Explanation of various bridge circuits, sensors, cathode ray oscilloscopes, digital meters, potentiometers, transducers and more. We explain the working principles of various measuring instruments and measurement systems.
Learn about different types of electronic devices. We can switch to Basic Electronics, Semiconductors, Diodes, Transistors, LEDs, Printed Circuit Boards, MOSFETs and more.
Digital electronic transactions with digital or disconnected signals. We cover binary number systems, binary arithmetic, Boolean algebra, de Morgan theorems, K-maps, logic gates, and other number system transformations, including binary. We also explain basic electronic circuits of various logic gates.
Learn about electric power generation systems, including heat, hydro, nuclear power generation, solar panels, wind power generation, cooperatives and more. We explain the working principles and characteristics of various components of power plants such as boilers, turbines, solar panels and wind turbines.
Learn about three types of electric switchgear systems – low voltage switchgear, medium voltage switchgear and high voltage switchgear – and separate components of electric switchgear systems. We explain the process, testing, commissioning and maintenance of various parts of switchgear – including CB, CT, CVT, PT, isolator and more.
Articles related to electric power transmission systems. Learn about the various transmission parameters, the various materials used to construct the transmission line, the HVDC system, and the various theoretical methods in power transmission. We discuss the design of transmission towers and their foundations.
Electric generators are the most expensive as well as the most expensive components of a power system. AC and DC generators are basically two types of generators. One of the most common forms of AC generators is an alternative. We have provided several articles about generators in this generator section of the website – to help you understand the basic idea of generators.
