BECAUSE THE VOLTAGE LEVEL IS DEPENDS UPON THE INSULATIO OF
THE WINDING & CURENT LEVEL IS DEPENDS UPON THE THICKNESS OF
WINDING IN CASE OF GENERATOR OR MOTOR. SO, INCASE OF
HIGHVOLTAGES THE THICK OF INSULATION IS KEEP VERY LARGE &
ALSO INSULATION IS COASTLY AS COMPAIR TO THE COPPER & HENCE
GENRATION OF ELECTRICITY IN LOW VALUE VOLTAGE.

Dear Respected sir how to test ABB REX521 protection relay by relay tester.
I am designing new project sub station with 220 kV / 11 kV, 40 MVA capacity. This project have many recifier sets, which can generate 3rd harmonics. Now I have to select vector group of This transformer. To minimise 3rd harmonics, what care should I take in selection of Transformer Vecrtor group? If it is Y-Y with open Delta tertiary then what should be the rating & voltage of Tertiary Winding?
