Why temperature rise test is conducted in bus bars and
Isolators?

Answer Posted / vijaykumar

if u use conventional bus arrangement systems like RR-YY-BB
then because of Skin effect and proximity effect there will
be increase of the temp of the bus bars because of uneven
distribution of currents.So better to go for interleaved
busbar system.RYB-RYB.Reply me if u feel my answer is wrong
or right
