Answer Posted / technic man
Simply Because the generators which are used from the
beginning of build a system , have a standard output
frequency 50HZ so all equipments and instruments you want to
supply it must have a standard freq. 50HZ
And if the generators have a standard output freq. 60Hz , so
all instruments also must have input frequency 60HZ.
that's the idea
And it has no relation with any technical issue
