“…The selection of the discharge current of an SPD requires the evaluation of the peak value and wave shape of the possible current flowing through the SPD [10,11,12]. In fact as general rule, SPD shall withstand the energy relevant to the perspective current at the installation point and, at this value, the protection level Up shall be lower than the required one.…”

The present paper aims to illustrate the influence of the main factors which affect the selection and installation of an SPD for the protection of electrical and electronic systems against overcurrent and overvoltage due to direct lightning flash to a structure. The two most typical SPDs are considered, namely switching and limiting type. Simple rules are established for the selection of effective SPD with regard to the discharge current, its protection level and location. © 2012 IEEE

“…The parameters of I imp or I n are relevant to SPD class I tests and SPD class II tests, respectively, according to the IEC 61643-11 standard [8]. The wave shape 0.25/100 s, due to high value of current steepness, is responsible for highest voltage drop on connection leads of SPD and for the reflection in the circuit between apparatus and the closest upstream SPD and then affects the SPD dimensioning in terms of protection level (U p ) [17][18][19]. The lightning current striking the line is represented by Heidler function [14][15][16].…”

In the present paper practical recommendations and procedures are proposed for selection of an SPD system with aim to protect, with a given probability, electronic and electrical apparatus within a structure against overvoltages coming from different sources of damage as defined by IEC 62305 [1]. The investigations are based on several computer simulations, by means of commercial transient software EMTP-RV, at the typical basic arrangement consisting of an apparatus within a structure influenced by direct flashes to the structure (source of damage S1), flashes to ground nearby the structure (source of damage S2), flashes to power and communication lines connected to the structure due to flashes to and near the lines (sources of damage S3 and S4). This work is executed in focus on the frame of discussion on recommendation of IEC/EN 62305 [1] for the selection of coordinated SPD system able to reduce the failure of the apparatus with a given probability.
