Power lines connect the power generation station to a variety of customers dispersed over a wide region. Power transmission is done using varying voltage levels and power line cables. Power line cable characteristics and the number of crossovers play an important role in determining the kind of communication technology that needs to be used. Based on the voltage levels at which they transfer power lines can be categorized as follows
1. High-tension lines: These connect electricity generation stations to distribution stations. The voltage levels on these lines are typically in the order of hundreds of kilovolts and they run over distances of the order of tens of kilometers.
2. Medium-tension lines: These connect the distribution stations to pole mounted transformers. The voltage levels are of the order of a few kilo volts and they run over distances of the order of a few kilometers.
3. Low-tension lines: These connect pole-mounted transformers to individual households. The voltage......
