I Think You Should Know This

Some fun facts to make things lighter....
Have you heard of the Corona Effect? No I'm not talking about the virus sweeping the world. This is something related to electric transmission.
During transmission of EHV(Extremely High Voltage), say upwards of 132 Kilo Volts, you'd find a bright bluish purple haze over the transmission towers right where it carries the conducting wires mostly on rainy or humid nights. That's what we electrical engineers call corona. It happens because the extremely high voltage within a short gap between two conductors, causes the air between the conductors to breakdown and become partially conductive. (Air is normally non conductor of electricity but the high voltage over a short gap is able to ionize the air, causing occasional sparks to pass, that's why you get to hear the zooming sound when you walk below a transmission tower). The air on ionization can even release gases like ozone and nitric oxide. It might look pretty but it causes substantial loss in the electrical network unless we take preventive measures like using corona-rings, increasing the space between two wires etc. Here's a picture of it. See if you have ever noticed it. Or next time just keep a look out for these pretty thingies. 馃檪

Is it the same for spark plugs where we see a blue spark jump ?

@in10RjFox Exactly!
