Question

For equilateral spacing of conductors of an untransposed three phase, we Have :



A.

Balanced receiving end voltages and communication interference 

B.

Balanced receiving end voltages and no communication interference   

C.

 Unbalanced receiving end voltages and communication interference

D.

Unbalanced receiving end voltages and no communication interference

Answer ( Option A)

Balanced receiving end voltages and communication interference 

Solution

An transposed three phase of length balanced in each (l/3) length. This phenomenon is called transposition of circuit.

                   

This balanced the receiving end voltages and communication interference. For equilateral spacing of conductors of an untranspoted three phase line.
