Answer / abhi

there are different arrangement for testing different vector group x mer's .The main purpose of testing is to avail that x mer's winding doesn't get damaged while transportation erection of x mer.

Answer / nibel

the vector group of the transformer wil be seen in the name
plate. for example if its dyn11 means delta star with
neutral.11 means 11 o clock is the phase angle between
voltage and current(30 deg lead)

Answer / arun

we can check the transformer vector group and polarity of
tansformer.ex.Dyn11 in name plate .11 "o" position we are
check th tansfomer

is this the formula of building wiring to get the main breaker.Watts/volts*.8%+higher motor*(25%)=ampere. yes or no or send the correct formula for building wiring.
