Simulate HVLC in MATLAB for Controlling Ground Voltage: A Review

Abstract

In communications and electronic engineering, a transmission line is a specialized cable or other structure designed to carry alternating current of radio frequency, that is, currents with a frequency high enough that their wave nature must be taken into account. Transmission lines are used for purposes such as connecting radio transmitters and receivers with their antennas, distributing cable television signals, trunklines routing calls between telephone switching centers, computer network connections and high-speed computer data buses. This article covers two-conductor transmission line such as parallel line (ladder line), coaxial cable, stripline, and microstrip. This proposed system model illustrates the principle of operation of an IVACE-based on fixed power supply connected to one of the two OGW of a fixed transmission line has best suited for developing the transmission network. Important areas of future research work on tower base earthing systems include (i) the installation ring electrodes of different diameters and depths around each tower footing and (ii) further experimental studies to clarify the conduction mechanisms of earth electrodes under high magnitude impulse current. The objective of the experimental work on ring electrodes for controlling ground voltage gradient would be reduce step and touch voltages in the proximity of tower footings.
