Class of accuracy in electrical measurements Class of accuracy in electrical measurements In electrical engineering class of accuracy is a figure which represents the error tolerance of a measuring device. The professional measuring devices are labelled for the class of accuracy. This figure is the percentage of the inherent error of the measuring device with respect to full scale deflection. For example, if the class of accuracy is 2 that means an error of 2 volts in a full scale 100 volt reading. In electrical engineering characteristics like current or voltage can be measured by an ammeter, a voltmeter, a multimeter, etc. The ammeter is used
Armature (electrical) design of the machine and its performance, affecting such factors as commutation in a DC machine or the waveform of an AC machine. Armature wiring is made from copper or aluminum. Copper armature wiring enhances electrical efficiencies due to its higher electrical conductivity. Aluminum armature wiring is lighter and less expensive than copper. Armature (electrical) In electrical engineering, an armature is the power-producing component of an electric machine. The armature can be on either the rotor (rotating part) or the stator (stationary part) of the electric machine. The armature interacts with the magnetic field (magnetic flux) in the air-gap; the
