The earthing system or earth electrode subsystem establishes the electrical connection between the building, structure or facility and earth. This connection is necessary for lightning protection, useful in power fault protection, and and in the minimization of noise. The earthing system should be tailored to reflect the characteristics of the site and the requirements of… 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 »
A contactor is an electrically controlled switch used for switching an electrical power circuit , similar to a relay except with higher current ratings. Contactor is in fact an electromechanical switch. Low-voltage Contactor is an electrically controlled switch used for switching an electrical power circuit, similar to a relay except with higher current ratings. A… Read More »
What is a balun? A Balun is special type of transformer that performs two functions i.e. impedance transformation and balanced to unbalanced transformation. The term balun is a contraction of “balanced to unbalanced transformer” Why do we need a balun? Baluns are important because many types of antennas (dipoles, yagis, loops) are balanced loads, which… 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 »
