Spark gap transmitters are not legal now because of the wide-band interference that they produce even with filtering. This disadvantage can be used as an advantage in radio frequency jamming by simply eliminating the filtering.
In modern usage, I’ve only seen Tesla coils used in welding machines. DC current does not like to jump a gap to start an arc and some types of welding, like aluminum welding, doesn’t work well being directly contacted with a DC electrode, as I understand it. Arcs are easy to maintain once started however. (Don’t question me about welding please because I’m not a welder but I have repaired the machines.) For aluminum welding, some machines will use a Tesla coil as a cheap way to generate high frequency in order to form an arc without touching the electrode to the metal. The arc then is conducting electricity energizing a relay to break the contact with the Tesla coil leaving only the DC component. The arc is still present—only pure DC now—so the relay continues to disable the Tesla coil. Once the arc is quenched, the relay drops out and the Tesla coil is again given power to re-establish the arc. Although other methods could be used, a Tesla coil is rugged, simple and extremely reliable. Using the drop-out relay makes the switching automatic.
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low-current, high frequency alternating-current electricity. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
Tesla used these circuits to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the 1920s, and in medical equipment such as electrotherapy and violet ray devices. Today, their main usage is for entertainment and educational displays, although small coils are still used as leak detectors for high vacuum systems.
