This paper presents an assessment of lightning protection schemes for overhead lines from
two aspects: protection performance and economic cost. Considering the random nature of …

The paper addresses the important issue of evaluating the overvoltages produced on a
power system by a lightning event. First, the theoretical formulation of the problem in the time …

In medium-voltage distribution lines, lightning outages associated with indirect strokes are
less frequent when surge arresters are installed at close intervals. In this case, the lightning …

Fragility modeling and real-time risk assessment can be widely applied to evaluate and
enhances the resilience of the power system to High-Impact and Low Probability events. In …

The paper aims at defining a methodology to evaluate the lightning performance of a system
of overhead distribution lines. As is well known, the evaluation of the lightning performance …

In the usual practice, the evaluation of overvoltages due to direct lightning strikes to
overhead power lines is focused on the representation of the effects of the lightning current …

Direct lightning strikes mainly determine the lightning performance of medium-voltage
distribution lines with surge arresters installed at close intervals. Recent studies have shown …

This paper proposes the application of a recursive stratified sampling technique for
improving the assessment of the lightning performance of power distribution lines through …

This paper presents the performance evaluation of various lightning protection schemes of
medium-voltage overhead lines using risk-based insulation coordination method. The …

Energy supply interruptions or blackouts caused by faults in power distribution feeders entail
several damages to power utilities and consumer units: financial losses, damage to power …
