Power line impedance is a very important parameter on the design of power line
communications (PLC) modem architecture. Variations on the impedance of the power line
affect the communications circuit performance. In order to determine impedance of the
power lines, measurements were carried out in Turkey at frequencies ranging from 10 to
170 kHz, (CENELEC A,B,C,D bands). Measurements were conducted in three categories:
rural, urban and the industrial power lines.
