Could anyone tell me how to size the autotransformer size for starting of 6.0 kV,50Hz,1600 kW induction motor by autotransformer start method.The tap voltage required is 80%,65% and 50% of nominal line voltage.
Thank you
Can anyone know how to calculate the transformer thermal damage curve for transformer designed and manufactured according to IEC 60076.I have checked and found only ANSI short circuit withstand curves/equation but can not find IEC short circuit withstand curve/equation.Or can I use ANSI...
Hi friend,
I have faced the problem of generator protection setting of back up underimpedance protection for generator protection as follows;
1)First theory: I have found one relay engineer set this 21 mho function having two zones setting as followings,1st zone set to cover in excess of...
