Answer / c.hari balakrishnan
SWITCHGEAR : -
There is no specified value of leakage current,Normally it
depends on how much load is connected.Normally it is in
milliamps.For example : In 11kV SWGR we highpot with 20bays
(indoor SWGR)we can get around 20 to 30 mAmps...
Cable: -
for cables normally we can get around very low Milliamps...
