Electrical leakage and quality for powergrid

Electrical leakage and quality for powergrid

Electric and magnetic fields are invisible areas of energy (also called radiation) that are produced by electricity, which is the movement of electrons, or current, through a wire. An electric field is produced by voltage, which is the pressure used to push the electrons through the wire, much like water being pushed through a pipe.
