Intro to Transmission Line

In the long transmission line model, parameters are considered to be lumped for better accuracy.

• True

• False

The equivalent circuit of a transmission line is always modeled in three-phase format only.

• True

• False

As transmission voltage increases, both the cost of conductor material and the cost of insulation and terminal equipment increase.

• True

• False

The nominal π and T models are used to represent short transmission lines.

• True

• False

The main function of a transmission line is to transport electric energy with minimal losses over long distances.

• True

• False

The economic transmission voltage is typically calculated using empirical formulas rather than detailed cost analysis.

• True

• False

Shunt conductance is always considered in the modeling of transmission lines because it significantly affects current flow.

• True

• False

Suspension-type insulators consist of porcelain discs connected in series, typically used for voltages above 33kV.

• True

• False

A flashover destroys the insulator permanently.

• True

• False

String efficiency improves when shunt capacitance is decreased.

• True

• False
