Hi,
I have a industrial ozone generation system, composed of 800 corona discharge lamps. They operate at 35 kV and the current in each lamp is of about 40 mA.
Due to environmental conditions, occasionally an electric arc occurs between the metallic outer surface of the lamp and some other metal part of the system. This is is a factor that is hard to control, due to dust, umidity etc.
When this electric arc occurs, the high current causes the protection system to cut power for all the system. What I'm looking for is a simple and cheap solution to identify in which lamp the electric arc originated from. Ideally, what I'd like would be a low voltage/current signal so I can read it from a microcontroller and display the faulty lamp. Any ideas on how could I get this signal on this situation?
Kind regards,
Victor
