Although we type words and letters in the computer, the computer does not understand the words and letters. Rather, those words and letters are translated into numbers. Computers “talk”… Read More: Number Systems for Dummies »

Vacuum Contactor vs Circuit Breaker Selection Considerations

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: Vacuum Contactor vs Circuit Breaker Selection Considerations »

Balun Transformer – Balanced vs Unbalanced Transmission Lines

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: Balun Transformer – Balanced vs Unbalanced Transmission Lines »
