Lightning-induced overvoltages have a considerable impact on the power quality of overhead distribution and telecommunications systems, and various models have been developed for the computation of the electromagnetic ...

The objective of this paper consists of presenting a design of expert system that assists the procedures involved with the protection specification of transformers and equipments against atmospheric discharges, allowing ...

The principal function of an Electric Power System is to supply energy power, maintaining acceptable service conditions. Where, the insulation coordination and protection relays play a crucial role. However, it is clear ...

The work presents an evaluation of the conformity of the installations of protection systems against lightning and grounding in relation to Brazilian standards. Using a methodology that through evaluations through surveys, ...

Lightning strikes are unpredictable events that have a high destructive effect. A lightning strike can occur between clouds, or between cloud and land. Hitting the earth with an atmospheric discharge can cause damage, thus ...

The overvoltage level of a system is strongly dependent on the connected loads and with more precise models, better and more reliable simulation results are obtained. This paper presents the input impedance characteristics, ...
