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]
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.

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.
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 ...
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 ...
In electronics testing and servicing, an isolation transformer is a 1:1 (under load) power transformer used for safety. Without it, exposed live metal in a device under test is at a hazardous voltage relative to grounded objects such as a heating radiator or oscilloscope ground lead (a particular hazard with some old vacuum-tube equipment with ...
