This paper proposes an investigative research on the Canadian National Tower (CN Tower) grounding system voltage response and current parameters passing through it. The CN Tower grounding system is modelled considering (i) a DC resistance, (ii) a frequency dependent models. The CN Tower and the incident lightning strike were modeled using Electroma...

... be found in [5]. The presence of any upward-connecting leader is neglected in the model. The channel that extends fro m the tower's tip to the return stroke channel front is modeled as a transmission line (TL). TL model is used to describe the spatial and temporal distribution of the lightning return stroke current along the channel as shown in Fig. 3. In this figure, Z ch and L ch represent the characteristic impedance and the length of the channel and Z L represents the equivalent impedance of the leader channel at the return stroke wave front. The injected current to the tower I inj is a part of incident current injected at the attachment point. I inj propagates in object with ...

Photovoltaic (PV) systems are subject to nearby lightning strikes that can contribute to extremely high induced overvoltage transients. Recently, the authors introduced a 3D semi-analytical method to study the electromagnetic transients caused by these strikes in a PV module. In the present paper we develop an improved model of the PV module that:...
