Product Information

How does a Tesla coil work?

Tesla coils are systems known as dual mode resonant transformers. This means they use the natural phenomena of resonance to take a small voltage, like what comes out of a wall plug, and transform it into the much higher voltage used to create an arc. This works the same way as shaking a flag pole – a small motion at the bottom is amplified to a big motion at the top. ETP has a Tesla coil embedded in each product and the arc is used in applications in high voltage leak or holiday detection and air plasma (corona) treatment. If you believe you have such an application and are interested in our products, please contact with your inquiry.

Which applications are most common for ETP’s Tesla coils?
