Cahier Technique Schneider Electric no 207 / p 4 1 Three-phase asynchronous motors This section covers 3-phase asynchronous motors, the most commonly used motors for driving machinery The use of this type of motor has become the norm in a large number of applications because of its numerous advantages: it is standardized, rugged, easy to
Cahier technique no 83
Cahier Technique Schneider Electric no 83 / p 6 It is observed from the vector diagram (see fig 2 ) that I′ 1 has a higher value than I1 and is out of phase, in front of I1, a vector considered to be in phase with the voltage U existing between the extremities of the 3 elements which are at the same potential In the same way, in element 3: ′

Cahier Technique Schneider Electric no 141 / p 6 In France v On EHV networks (400 and 225 kV), various reclosers are used: - slow single-phase reclosers tripping in event of single-phase faults: breaking time is around 1 5 to 2 s, - slow three-phase reclosers (multiphase faults), whose operation depends on voltage
