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.....

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
