If you need to learn everything about thermoelectric generator then this page is for you. Thermoelectrical power generator is a solid state device that facilitates direct conversion of thermal energy into electrical energy. Thermoelectric generators function like heat engines, but are less bulky and have no moving parts and are completely silent. The best part… Read More »
The Hall effect was discovered 18 years before the discovery of electrons i.e. in 1879 by Edwin Herbert Hall. This achievement happened when he was working on his doctoral degree at the Johns Hopkins University in Baltimore, Maryland, USA. What is Hall Effect The Hall effect is the production of a voltage difference (the Hall… Read More »
To compare the application of medium-voltage circuit breakers and of fused contactors, we must understand the basic characteristics of each switching technology. The below table shows the major characteristics of medium-voltage circuit breakers and medium-voltage fused contactors that influence the application. Of course, the table entries are generalized, and the information varies by the voltage… Read More »
What is a Digital Multimeter? Digital Multimeter also famous as DMM is simply an electronic instrument that measures electrical parameters including AC/DC volts, AC/DC current, resistance. In addition digital multimeter may have a variety of special features that are designed for a wide number of applications like frequency, temperature, capacitance and continuity in a circuit.… Read More »
The phenomenon of ionization of surrounding air around the conductor, hissing noise and production of Ozone gas in an overhead transmission line is known as Corona Effect. Corona discharge is a process by which a current flows in a conductor with a high potential into a neutral fluid, usually air, by ionizing that fluid so… Read More »
In this method of inter-connection the similar ends either the ‘start’ or ‘finish’ are joined together at point N. This common point N is called star point or neutral point. Ordinarily only three wires are carried to the external circuit giving 3-phase, 3-wire star connected system but sometimes a fourth-wire, known as neutral wire is… Read More »
