Harmonic performance of single phase transformer with DC biased
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Direct current (DC) flowing through the earthed
neutrals of transformer windings causes a DC
component in magnetizing current. Owing to nonlinearity,
the waveform of this current is strongly
distorted. A high enough ...
Induction motor behavior due to unsymmetrical and symmetrical faults
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Voltage sags are generally caused by faults on transmission and/or distribution systems. The voltage produced may be either unsymmetrical or symmetrical, depend on type of faults. Unsymmetrical fault is faults caused by ...
