SA Power Networks 1 Electric and Magnetic Fields
... Electric fields are found wherever voltage is present. The higher the voltage and nearer the source, the stronger the field. As long as an appliance is plugged into an active power outlet, it emits an electric field. The appliance doesn’t need to be running. Magnetic fields Magnetic fields are found ...

High voltage
The term high voltage usually means electrical energy at voltages high enough to inflict harm on living organisms. Equipment and conductors that carry high voltage warrant particular safety requirements and procedures. In certain industries, high voltage means voltage above a particular threshold (see below). High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to demonstrate arcing, for ignition, in photomultiplier tubes, and in high power amplifier vacuum tubes and other industrial and scientific applications.
