Answer / sandeep samant

It is due to skin effect of ac current. The most of ac current flows through the outer(circumference) part of conductor. So we use bundle conductor to increase the circumference area of conductor. it increases the current carrying capacity of conductor.

Answer / vikalp dhiman

Extreme High Voltage carrying lines causes corona loss.to reduce this loss we use bundled conductors.These consists of 2,3,or many more conductors in bundle.Each conductor carries equally distributed among these conductors(in bundle).Due to this corona loss reduces
CORONA LOSS--High voltages ionises nearby air which causes power loss and affects communication wires.

Answer / ali

Bundle Conductors are preferred instead of single conductor because:
-reduces voltage gradient
-affect critical corona voltage
-reduce inductive reactance
-reduce Radio Intereference

Answer / amit kumar beniwal

In AC transmission line if conductor Diameter increase then
Skin effect increase due to high concentration of current
near outer surface of the conductor & due to this cause
Corona loss also increase.SO we use bundle conductors
instead of single conductor.
BUNDLE CONDUCTOR -When we combine number of conductors as a
conductor whose Diameter is small is called Bundle conductor.

CORONA LOSS-Hissing noise & luminous glow due to high
voltage ionises nearby air which cause power loss and also
effect communication signals.

Answer / rakesh kumar

we know that resistance is inversely proportional to the area of conductor, in bundle conductor two or more conductor make a bundle which increases the area of the conductor. this means we reduces the resistance of the conductor and the power loss is reduces.it also helpful to reduces the skin effect and corona loss..............

Answer / ritesh a. wajari

because of more is the diameter less is the corona loss,
genaraly in bundle there is four conductor so it maintain the more distance so it reduced the corona loss.

Answer / saleem pasha

Voltage gradient is reduced because of less diameter of conductor hence bundeled conductor is used instead of single conductor for high voltage transmission line

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
