current cyring capacity of .75sqmm copper cable
Answers were Sorted based on User's Feedback
current capacity of copper can be taken as 2.5 A/sq mm but
for generators it is taken as 1.5 A/sq mm.For duration of
less than 4 hours 6A/sq mm

Answer / shahzad
current density =current/area
as the current density for copper is normaly 3 so
3=current/.75
current=3*.75=2.25A

725KW Three DG set Synchronised but DG no-1 power showing 750KW DG n0-2 power showing 500KW DG no-03 showing 500KW. DG is Shynchronised but why this different power showing?
I have a 1000 kVA Transformer(11kV/0.415kV) and a APFC panel of 400 kVAR(LT).Now if i want to remove the LT APFC panel and install a HT(11kV) APFC panel on the HT side is the HT APFC panel will work same as the LT APFC panel(improve the power factor),if yes what will be rating of the HT APFC panel?what is the formula to calculate HT APFC panel rating???
i am using auto transformer for starting of induction motor to provide reduse voltages...but the principle of a tansformer according to definition"which transform energy to on circuit to another circuit with constant power and constant frequency". so if i am using reduse voltage then current obsely hige because power is same.but we use auto transfarmer for starting of induction motor to give low current.but here according to definition we are giving hige current.
