Why temperature rise test is conducted in bus bars and
Isolators?
Answers were Sorted based on User's Feedback
Answer / gajanan patil
bus bars and isolators are ratewd for contious power flow.
means they carry heavy currents which rises their temp. so
it vis necessary to test this devices for temp rise

Answer / srikanth
when resistor is decreases current in the conductor will
increase due to inversely proposational... and the current
and temperature is directly proposational.. when it
increases temperature increases directly...

It is require to do this test for protection design system. i.e to find short circuit rating of busbar and base on this design protection system.

Answer / 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

What is switch disconnector fuse?
in the directional overcurrent and earthfault protection,normally we are setting the angle 45 deg lead for phase fault overcurrent and -45 deg lead for earthfault fro forward direction.but both the fault are operating on the same angle region only.why?how the relay will response?
if we increase the frequency given to a transformer then wat will happen to the transformer size, whether it will increase?
can we use ELCB and RCBO in one db
In an LT pole, the line voltage is 415V. How is it converted to 230V into the house via the service cable?
what is eddy current loss?
why the making current is more than then the breaking current and if its true then its about a controling circuit or breaker power contact points
I If i have 2kv ups in which 38Amp *8battries hou many hour's back up i get from 600Watts
reason of capacitor failure or low voltage in alternator wtih 10kva dgset
what happenes if the core of the transformer saturates?
The size and construction of bushings in a transformer depend upon?
For a spring controlled governer the relation F = ar+b (F is the controlling force, r is the radius of rotation a and b are constants), indicates that the governer is
