Transposition of transmission line is done to

DC series motors are best suited for traction work because

Torque in d.c motor = k* φ * Ia
In series motor φ α Ia
Tα I²
N α 1/φ
N α 1/T

If the excitation of a synchronous generator fails, it acts as a

if excitation of synchronous generator fails, operate as induction motor

The corona effect can be minimized by increasing

Corona can be reduced by using large size of conductor, bundle conductor and hollow conductor.

A fixed step by step procedure for finding the solution of a problem on computer is called

An IDMT relay provides
