If the supply voltage is same (say 440V) whether a system
designed for 60 Hz frequency will work with 50 Hz frequency
or not , if so pl. give clarification.
Answer Posted / shahin
Dear all I've seen that all r telling dc motor, ac motor,
converter etc. ABB has asked for a system not for motor/
inverter. As the equaiton of joysbag reduction of frequency
of 10% will cause increment of 16.67% of flux. Though the
system is designed about 60Hz. Then the system component
may be malfunctioning. All of equipments of the system must
be changed as frequency has changed.....
