nameplate rating: The full-load continuous rating of a specific electrical apparatus, like a transformer or generator, under specified conditions set by the manufacturer.
nano (n): A metric prefix meaning one-billionth of a unit, or 10 ⁹.
National Electrical Code (NEC): A national code of standards and practices for the electrical and electronics industry.
NEC: National Electrical Code.
negative resistance: The characteristic of a circuit in which current varies inversely with applied voltage.
negatively sequenced: Occurs when a three-phase electrical quantity, such as voltage, current, or power, crosses the zero line in the order of ACB rather than ABC.
NEMA: National Electrical Manufacturers Association.
network: A system of transmission and distribution lines cross-connected and operated to permit multiple power supply to any principal point on it. It provides a high level of reliability by restoring power quickly to customers during an outage by switching them to another circuit.
neutral: The grounded junction point of the legs of a wye circuit or the grounded center point of one coil of a delta transformer secondary.
neutral conductor: The conductor in a three-phase wye system that acts as the return conductor by conducting the resultant current in an unbalanced three-phase system. It bonds to ground on the output of a three-phase delta-wye transformer.
neutralizing winding: An extra winding that cancels harmonics developed in a saturated secondary winding and produces a sinusoidal output waveform from a ferroresonant transformer.
node: A terminal of any branch of a network or a terminal common to...
