what is the difference b/w winding insulation class and winding temperature class?..

Answer / a.hanumathu

winding insulation class is related to the capability of
short ckt of winding with other conducting part like
stator.and wndg temp class is related to ability of
conducting without melting or loose of insulation.

what is the difference b/w winding insulation class and winding temperature class?..

Answer / rvg

winding insulation classification is nothing but a group of
materials arranged in the order of insulation resistivity
in terms of Kv per mm.

winding temp. class is related to temperature withstand
capability of winding insulation.
