| Abstract |
Voltage sags and voltage interruptions are huge
power quality problems for many industries. Voltage sags cause
tripping of asynchronous machines by undervoltage or
overcurrent protection and in some cases saturation of the flux.
This paper gives a basic understanding of how voltage sags
change the stator flux in line-operated asynchronous machines
and under which circumstances saturation will occur. Most
voltage sags will cause saturation. Flux saturation results in both
large currents and torque; these may fasten the aging of the
machine. |
