Investigation of Lightning-Initiated Flashover Faults in Medium Voltage Overhead Lines - Modelling and Experimental Evaluation

, 2016
Lightning can cause flashovers on Medium Voltage (MV) lines from both direct and nearby strikes. The work presented in this dissertation thoroughly investigates the characteristics of lightning-initiated flashover faults, expected overvoltage stress and ...

Investigation on the Resonant Oscillations in an 11 kV Distribution Transformer under Standard and Chopped Lightning Impulse Overvoltages with Different Shield Placement Configurations

Energies, 2019
This paper presents an investigation on the resonant oscillations of an 11 kV layer-type winding transformer under standard and chopped lightning impulse overvoltage conditions based on calculated parameters. The resistances, inductances and capacitances

PERFORMANCE STUDY OF OVERVOLTAGE CUTTING BY LIGHTNING ARRESTER DUE TO LIGHTNING INDUCTION

TESLA: Jurnal Teknik Elektro
Lightning disturbances often cause induced overvoltages on 20 kV medium voltage distribution overhead lines, which can shorten equipment life and trigger power outages. This study aims to evaluate the cutting performance of two types of lightning arresters made of ceramic and polymer in reducing lightning-induced voltage surges through high-voltage ...

Test and simulation of lightning current distribution on a wind turbine blade

, 2014
Design of the lightning protection system (LPS) of complex wind turbine blades must take into account how current is distributed along possible paths to ground. The flow of lightning currents can result in overvoltages which in turn can ignite sparks and

Corona Influence on Lightning Induced Overvoltages in MOV Protected Multiconductor Power Lines [PDF]

, 2001
The effects of corona on amplitude and distortion of lightning overvoltages in three-phase MV lines is investigated. The line is protected by surgearresters whose characterstics can be planned taking into account real ...

Lightning induced overvoltages on overhead lines shielded by nearby buildings

, 2016
In urban areas the presence of buildings is expected to reduce the amplitude of lightning induced voltages on overhead lines with respect to the case of open terrain. This paper presents a method for estimating such a reduction effect.
