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]
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.
Review of the artwork and its installation, including outlet and cord placement, by curatorial, installation, and electrical staff will help ensure the safety of the artwork. [9] Transformers: A transformer is used to convert electricity into use by the neon sign. When cataloging a neon artwork, the transformer type and age may be noted in the ...
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.
This is especially important when using transformers with fragile high-voltage windings, such as neon sign transformers (NSTs). Regardless of which configuration is used, the HV transformer must be of a type that self-limits its secondary current by means of internal short-circuit inductance. A normal (low Short-circuit inductance) high-voltage ...
High leakage reactance transformers are used for some negative resistance applications, such as neon signs, where a voltage amplification (transformer action) is required as well as current limiting. In this case the leakage reactance is usually 100% of full load impedance, so even if the transformer is shorted out it will not be damaged.
Neon lighting, a widely used form of cold-cathode specialty lighting consisting of long tubes filled with various gases at low pressure excited by high voltages, used as advertising in neon signs. Low pressure sodium lamps , the most efficient gas-discharge lamp type, producing up to 200 lumens per watt, but at the expense of very poor color ...
The Future Isn't What It Used to Be, 2015, neon artwork by Hubert Czerepok. The letters form a shape of Poland. The mid to late 1980s was a period of resurgence in neon production. Sign companies developed a new type of signage called channel lettering, in which individual letters were fashioned from sheet metal.
