boolean algebra: a simple mathematical system based on binary arithmetic and the basis for digital logic operations.
hi-pot: a high potential test where a high voltage is applied between the windings and the metal enclosure, core, or other windings.
megger: also known as a megohmmeter. This is an instrument designed for measuring insulation resistance.
milliohmmeter: an instrument that measures very small values of resistance.
multimeter: an instrument that functions as a voltmeter, ohmmeter or ammeter.
phasor: rotating vector.
prony brake: a braking method where a pulley is applied to a motor and a lever arm of known length is clamped around the pulley. A spring scale can be used to determine the torque of the motor by applying T = length X force.
