Hope you all are fine and good. I have one Question regarding to frequency and voltage as below.
In Asia, Europe and some other countries there is a 50 Hz and in some other countries there is 60 Hz frequency.
Can anyone advise me the advantage of 60Hz over 50Hz
same also in voltage as below;
In some countries there is
380 Volt ( line to line ) 3ph
220 volt ( line to neutral ) 1ph
In some other there is
240 volt (line to line ) 3ph
120 volt ( line to line ) 1ph
So, please advise me the main advantage of 60Hz, 120 volt 1ph or 240 volt 3ph Over the 50Hz, 220volt 1ph, 380 3ph.
Eventhough we know, using 60Hz, 120 volt 1ph or 240volt 3ph cost us much more than 50Hz, 240 volt 1ph, 380 volt 3ph in underground ditribution and cable sizing.
