Investigation of lightning and commutation overvoltages in overhead lines.
This master's thesis investigates overvoltage processes caused by lightning discharges and switching operations in 110 kV overhead power transmission lines. Different types of overvoltages, their impact on the power grid, and potential protection devices

Lightning-induced overvoltages transferred from medium-voltage to low-voltage networks
Simulation results relevant to realistic configurations of medium-voltage (MV) and low-voltage (LV) distribution systems provide useful information to evaluate both the expected level of power quality problems on LV networks due to lightning and the ...

Lightning simulation of a combined overhead line/cable connected GIS [PDF]
, 2008 The paper concerns different investigations of lightning simulation of a combined 170 kV overhead line/cable connected GIS. This is interesting due to the increasing amount of underground cables and GIS in the Danish transmission system.

Lightning-induced overvoltages in medium voltage distribution systems and customer experienced voltage spikes [PDF]
, 2010 In Finland, distribution transformers are frequently subjected to lightning strokes for which they are continuously protected by spark-gaps. So, the breakdown probability of medium voltage (MV) spark-gaps is modeled using the Gaussian distribution ...

Lightning Performance on Transmission Line Towers
A method of transmission tower models construction for atmospheric overvoltages performance studies is presented. The overvoltage waves produce electric fields along the tower, the shielding wire and along the conductor. EMTP program has been selected as
