Low Voltage Transformers. 1  A low voltage transformer literally transforms the standard line voltage in your home or business (120 or 277 volts) to a lower 12 or 24 volts. This lets you safely supply power to popular low voltage lighting systems like recessed can lights, pendant lights, puck lights and outdoor light fixtures. 123.
By means of some fast talking and a $175 withdrawal from the treasury of Lord British, a 14,400-volt, 5,000-watt power-pole transformer was procured from the City of Austin's electric utility. This transformer, driving a rotary spark gap, provided excitation to the Tesla coil's primary resonant circuit. Normally used as a step-down transformer for power distribution purposes, the power-pole transformer was wired backward to step the 110- or 220-volt line voltage up to 14.4KV.
