Basics A transmission line has a constant line impedance (Zo) when operated well above it's corner frequency. This is the published Zo line impedance value. Well below the corner frequency the line impedance increases one order of magnitude for each two decades of frequency decrease. ...

IV. VALIDATING LINE IMPEDANCES WITH FIELD DATA Now that we have discussed the basics of line impedance calculation, we present a method to validate line impedances using data gathered by relays after a line-to-ground fault. The only data that are needed to perform this calculation are voltage...
Flows of active power and reactive power through every transmission line and transformer were computed for all case studies. Active power flows through all transmission lines of the test system for all study cases are provided in Table 4. It can be seen that transmission elements became overloaded...
of which negligible current is induced. For something like a current transformer, which takes advantage of inductive coupling, it may have thousands of windings in a comparable amount of space. Even for inductive coupling of a transmission line to things like fences running alongside power lines, ...
