Electric Shock From The Anode High Voltage

By on April 11, 2009


Do you know the feeling of being hit by the high voltage arc from the anode of the CRT Monitor? Yes i was hit by the blue arc generated by the flyback transformer few times during my early day in this repair field. For your information the voltage generated by the flyback transformer is 24 Kilo volt but because of the small current (about 25 to 30 microampere) this arc was not that fatal to my body. I felt pain and slight numbness in my hand for few hours after accidentally hit by the arc. Actually i did not know that the arc could have the capability to jump over (more than an inch) from the anode cap. The cap rubber was loosen and the arc just hit my hand when i’m trying to do some troubleshooting work while the Monitor is still “On”.

If you are in this line please do not give up just because of this high voltage thing. That time i was still new in this field and no one share with me about the danger of the high voltage. Since you now know about the arc that can jump over an inch when there is a leakage in the anode cap or whatever reason then place some extra precaution on that area especially when you have turn “On” the Monitor/TV for troubleshooting purposes.

    Hi Raga,
    Sorry i do not have the schematic diagram. That picture was meant just to show you how the arc look like. Try seacrh from google about tesla coil and you will find lots of project related to high voltage

    Hi Drewman,
    Sorry i do not have the spec because the photo was taken from other source. Guess you need to visit youtube and type in Tesla coil and you would see lots of project similar to the photos and you can email the owner.

    Hi Zifan,

    You may get many of this high voltage project by typing "Tesla Coil" in Google.
