Answer / s c budhiraja

Short Circuit fault levels of LT systems are low & all LT
cables can bear short Circuit faults. But problem with the
LT cables is of voltage drop.For this voltage drop
calcultions are done to see if the voltage drop is within
the permissible limit for the selected lenght of cable
being used for the rquired current.

Answer / k.prakashchandra

No cable is designed to carry SC current continuously and it
can withstand SC current for very short period.That is why
the protection is provided.

Answer / k.prakashchandra

Cables are not designed for short circuit current as
protection is provided. They can withstand SC currents for
short durations.
