An original setup to measure grounding resistances using fast impulse currents and very short leads
Electric Power Systems Research, 2019Abstract This paper presents a method for measuring grounding resistances, which is based on the use of fast impulse current and short leads on the auxiliary measurement circuits. Usually, the conductor length of the voltage and current circuits used in grounding resistance measurements may be quite long depending on the grounding characteristics ...

Lightning strikes may cause a rise in transmission tower potential which could produce a tower-to-phase flashover. This paper presents a computer-modeled technique applied to study this phenomena. 120 kV and 315 kV power lines have been modeled. Transmission tower potential is presented.
