Dictionary of Electrical Engineering

Commonly used terms in the Electrical industry.

breakdown strength
voltage gradient at which the molecules of medium break down to allow passage of damaging levels of electric current.
field strength
in general terms the magnitude of the electric field vector (in volts per meter) or the magnitude of the magnetic field vector (in ampere-turns per meter). As used in the field of EMC/EMI, the term is applied only to measurements made in the far field and is abbreviated as FS. For measurements made in the near field, the term
electric field strength (EFS) or magnetic field strength (MFS) is used, according to whether the resultant electric or magnetic field, respectively, is measured.
GT
common notation for transducer gain in amperes/volt.
gas tungsten arc welding (GTAW)
a welding process that produces coalescence of metals by heating them with an arc between a nonconsumable tungsten electrode and the parts to be joined. The process is used with shielding gas and without the application of pressure. Filler may or may not be used.
magnetic length
the effective distance between the north and south poles within a magnet, which varies from 0.7 (alnico) to 1.0 (Nd-FeB, SmCo, hard ferrite) times the physical length of the magnet.
pigtail
short electrical conductor used to connect the brushes of an electrical motor or generator to the external electrical connections of the machine.
trace length
the physical distance between electronic components connected by a circuit path.
