Answer Posted / dixit
mcb
is a circuit protecting device which has a definite current rating which protects selective rating of the MCB which we choose.
MCCB
is also a circuit protective device we can change minimum to maxium value of current rating which can select .
ELCB
which sens the leakage current if any in the circuit,and trip the circuit immediatly

how to calculate transformer load?
How can calculate the earthing strip of Copper/GI for rating of 30kV,discharge current 10KA Lightning arrester.
As per the Anchor capstan motor specification, full load current is 200A. starting current is 1750 A and acceleration time is less than 8 seconds. Please guide for selection of cable size.
Why human body feel electric shock?
A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.

Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
