Work Safely With High Voltage: 5 Steps – instructables, Work Safely With High Voltage: There are a bunch of great instructables and other projects on the interwebs that involve high voltage power supplies. Most include a disclaimer that says some variant of "if you have any sense, don’t do this project." But rarely is there a reason
Ignition Coil High Voltage Display: 6 Steps (with Pictures), Ignition Coil High Voltage Display: A common automotive ignition coil can generate an output voltage on the order of 30,000 volts. This is a sufficient voltage to produce arcs which jump an air gap of an inch or more. Driven properly they can also be used to create a Jacobs Ladder
Voltage optimisation, Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage ‘optimisation’ devices have a fixed voltage adjustment, others electronically regulate the voltage automatically.
