14 terms of particular importance when discussing arc flash hazards

Electrical arcs Electrical arcs form when a medium that is normally an insulator, such as air, is subjected to an electric field strong enough to cause it to become ionized. This ionization causes the medium to become a conductor which can carry current. The phenomenon of electrical arcing is as old as the world itself. Lightning is […]

4 ways in which noise can enter a signal cable and its control – Part 1

Few words about interference… Noise, or interference, can be defined as undesirable electrical signals, which distort or interfere with an original (or desired) signal. Noise could be transient (temporary) or constant. Unpredictable transient noise is caused, for example, by lightning. Electrical noise occurs or is transmitted into a signal cable system in the following four […]
