You must have noticed that, when a major appliance is turned on (such as an AC unit, garbage disposal,
etc.), your house lights dim momentarily. This is the effect of the RL circuit formed by the inductance and
resistance of the transmission line and the loads (light bulbs, appliance, etc.) In fact, even a single straight
wire has inductance. The inductance (and the resistance) of a long transmission line can be problematic if
the system is not properly designed.
The voltage on a power transmission line is alternating current but the effect of transmission line can be
simulated by a DC circuit as shown below, where R=0.005 2 /km and L=0.04 H/km representing the
resistance and inductance of the transmission line per km relationship that is with the ration: L-8 R.
In the circuit, Right =160 represents light bulb resistances, R₁ = 7
represents the resistance of a
'major appliance', and the switch indicates when the appliance is turn on.
