On the secondary side of a distribution transformer, we use
1c x 630 sq mm cable. Why dont we use 4 core cables instead
of 1 core cables on the secondary. Why we use aluminium
cable glands on the outgoing instead of brass cable glands?

Answer Posted / k.prakashchandra
Cables of above 250 sq mm come in single core only in view
of the weight, workability and replacement.Al glands are to
be used for Al cables to avoid bi-metallic contacts.

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.
