What Is Transient?
A common cause of trouble is transient voltages on the AC power lines. Transients are instantaneous voltage spikes (high voltage short duration voltages). Transients can be commonly caused by lightning strikes or when electrical loads (electric motors) are switched on and off. These events can destroy electronic circuitry and corrupt stored data. In order to prevent the transient from reaching your electronic equipment you have to use an Unterruptible Power Supply (UPS) or surge suppressor with transient spike suppression.
By the way i’m having a 3 days basic electronic class for a 15 years old student and will post the photos to you tomorrow. I received another two testimonials from the buyers of my book Testing ElectronicComponents:
“Your testing methods are very useful for my work. Thanks for sharing so much.” John ChongSenior Field Application Engineer
Hi Jestine , I have finished reading your eBook, testing electronic components. I found that all information in the eBook is very, very, very good and so informative. This eBook is good for student like me. Thanks a lot for the eBook. This is the first eBook that I have not regret to buy it. I will wait for your next eBook in electronic repairing. Once again your eBook is awesome!!! Ali AbuStudent
