An iron cored neon-sign transformer, with a 9-volt battery for scale. A neon-sign transformer (NST) is a transformer made for the purpose of powering a neon sign. They convert mains voltage in the range 120-347 V up to high voltages, in the range of 2 to 15 kV. These transformers supply between 18-30 mA; 60 mA on special order. [1]
When cataloging a neon artwork, the transformer type and age may be noted in the artwork record, along with a reminder about potential future transformer replacements. An electrical engineer or professional should be consulted to identify the voltage type and requirements of the artwork's transformers. [7] Like other media, neon artworks should ...
This design is favoured when a relatively fragile neon sign transformer is used. Alternative circuit configuration. With the capacitor in parallel to the first transformer and the spark gap in series to the Tesla-coil primary, the AC supply transformer must be capable of withstanding high voltages at high frequencies.
Gas filled tubes and neon lamps have also been used as voltage references, primarily in tube-based equipment, as the voltage needed to sustain the gas discharge is comparatively constant. For example, the popular RCA 991 [2] "Voltage regulator tube" is an NE-16 neon lamp which fires at 87 volts and then holds 48–67 volts across the discharge ...
The neon available for purchase for a neon-sign shop often comes in glass flasks at the pressure of a partial vacuum. These cannot be used to fill a ball with a useful mixture. Tanks of gas, each with its specific, proper, pressure regulator and fitting, are required: one for each of the gases involved.
Neon sign. The neon sign is an evolution of the earlier Geissler tube, [11] which is a sealed glass tube containing a "rarefied" gas (the gas pressure in the tube is well below atmospheric pressure). When a voltage is applied to electrodes inserted through the glass, an electrical glow discharge results.
