What transformer is used for neon signs?
A neon-sign transformer (NST) is a transformer made for the purpose of powering a neon sign. They convert line voltage from the 120-347 V up to high voltages, in the range of 2 to 15 kV.
Do neon signs need a transformer?
Neon tubes require a high voltage at a low current to operate. This power is supplied by a specialized transformer. Secondary voltages typically range from 1,000 to 15,000 volts, and secondary currents range from 20 to 60 milliamps (and higher, for large diameter “cold cathode” tubing).
What kind of transformer is a Tesla coil?
resonant transformer
A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents. Tesla’s original circuits as well as most modern coils use a simple spark gap to excite oscillations in the tuned transformer.
How does a neon sign transformer work?
Neon signs use neon gas that is inert in nature. These signs are made up of tubes that are filled with this gas. This tube is supplied with high voltage obtained from the transformers. The high voltage supplied by them increases the kinetic energy of electrons in the neon atom.
How do you size a neon transformer?
To determine the required transformer voltage, multiply the operating voltage by 1.5 for argon/mercury and 1.8 for neon. Repeat this procedure for each tube in the sign, and tally the total for all tubes you want to put on one secondary circuit.
What voltage does neon use?
Neon lamps are recommended for 110 volt AC, 220 volt AC, and DC applications in excess of 90 volts. The lamps are available in miniature and sub-miniature sizes.
Do neon signs use a lot of electricity?
A red neon light’s typical energy consumption is at 3 1/2 to 4 watts per foot. If you continuously run a sign for 12 hours, a foot of red neon sign would typically use about 15.33 to 17.52-kilowatt-hours of electricity per year while a fluorescent model will take up 50 percent more than that.
Are neon signs a fire hazard?
Safety: While beautiful to look at, neon signs carry a safety risk if they are not maintained. Such risks include injury from broken glass or high voltage that can cause a shock or even become a fire hazard.

Are Tesla coils used today?
Today, this technology is still widely used and handheld Tesla or “Oudin” coils have many applications across industries such as oil & gas, pharmaceutical, construction and more to detect leaks or pinholes in a variety of materials.
How long does a neon bulb last?
between eight and 15 years
Most neon signs are expected to last between eight and 15 years, although many continue to function for much longer than that. Leaving a sign switched on for prolonged periods can shorten its lifespan, and leave it at risk of overheating or sustaining damage from electrical surges.
Are neon signs AC or DC?
A neon light actually works using either AC (alternating current) or DC (direct current), but if DC current is used, the glow is only seen around one electrode. AC current is used for most neon lights you see.
How many NSTs are on a Tesla coil?
Lastly, I would like to offer my gratitude to Larry Desario and crew of Santa Maria Neon Sign Companyfor contributing 4 – 15,000 volt 60mA neon sign transformers (NST’s) to my cause. Only one NST still powers my Tesla coil. The other three died in the line of eperimental duty. Useful & Fun Tesla Links
Which is the best neon sign transformer to buy?

What do you need to make a Tesla coil?
6 Glass bottles (Snapple bottles work really well) Oil (I used canola. Mineral oil (horse laxative) it preferable as it doesn’t mold, but I didn’t have any.) And a HV power source such as a NST, OBIT, or other transformer that gives off at least 9 kV at around 30 mA. Put a small slot into the top of the pipe to wrap one end of the wire around.
What happens if you touch a Tesla coil?
Unlike some other high voltage experiments, a Tesla coil’s streamers can be very harmful. If you are shocked by the streamers, you will not feel pain, but your circulatory and nervous system can sustain severe damage. DO NOT TOUCH IT WHILE ON UNDER ANY CIRCUMSTANCES.
