Question

Question:Transmission line conductance is usually neglected in power system studies.

(a) True

(b) False

Short answer

Answer

The correct answer is option (a) True

Step-by-step solution

 Step 1: Explain transmission line losses

Generally, the transmission lines are designed such that they maintain a calculated strength of electric field equal to $\mathbf{20}\frac{{\mathbf{kV}}_{\mathbf{rms}}}{\mathbf{cm}}$ maintain on the surface of the conductors, in order to control corona.

This is because corona causes additional line losses (corona loss), communications interference, and audible noise.

Current discharge occur and conductance increases enormously in the case when electric field strength at a conductor surface exceeds the breakdown strength of air.

Explain further in terms of discharge

To avoid the discharge, the line conductance of the self is generally neglected in the transmission line theory

Thus correct option is (a).
