It is derived from IEC 619361:2010, incorporating IEC corrigendum March 2011 and amendment 1:2014. It supersedes BS EN 619361:2010, w

CENELEC corrigendum February 2013 adds further special national conditions for Iceland to Annex ZA.The UK participation i

6、n the preparation of EN 619361:2010 was entrusted to Technical Committee PEL/99, Erection and operation of power installations. Preparation of this national foreword was entrusted to PEL/99 with assistance from Technical Committee GEL/600, Earthing.A list of organizations represented on these commit

7、tees can be obtained on request to their secretaries.NOTE To ensure wide participation in the process, GEL/600, in particular, has strengthened its membership to include more representation from the UK Electricity Supply industry (TSOs and DNOs) and an earth test equipment manufacturer. Furthermore,

8、 detailed consultation has been carried out with The Energy Networks Association (ENA) through its Earthing Coordination Group.Background and developments to IEC/CENELEC documentsIn recent years, two documents have existed sidebyside covering, among other things, the earthing of high voltage install

9、ations. The first was HD 637 S1, Power installations exceeding 1kV, published in 1999 while the other was IEC 619361, of the same title, published in 2002. These documents were produced by working groups of the committees CENELEC TC/99X and IEC TC/99, respectively. As these documents were not publis

10、hed at the same time and the composition of the working groups was to some extent different, a situation arose such that significant discrepancies existed between these two documents, notably, concerning the fundamental safety criterion of allowable human body current and body impedance values under

11、 step and touch voltage conditions. This situation was not ideal, and an initiative was taken to develop a revision to IEC 619361 under maintenance team IEC TC/99 MT4 and to release it as a European standard. At the same time, a working group CENELEC TC/99X WG1 was formed to extract the earthing con

12、tent of HD 637 S1 and bring to publication a new European standard on earthing (EN 50522). Parallel voting of EN 619361 BS EN 61936-1:2010+A1:2014BRITISH STANDARDand EN 50522 was arranged, in order to achieve harmonization of the adopted electrocution safety criteria and both documents were publishe

13、d in 2010.Differences in the UK approach to earthing designThe differences in the UK approach to earthing are covered in the National Annexes of BS EN 50522 and relate to:1) Recognition of the probabilistic nature of electrical system safetyA new additional approach to earthing system design, based

14、on probabilistic methods, is outlined and developed in the National Annexes to BS EN 50522.2) Deviations of UK safety limits compared to IEC/CENELEC limitsAs a result of advice obtained from the UK Health and Safety Executive (HSE), consensus was reached between PEL/99 and GEL/600 that UK HV earthin

15、g systems have to be designed according to tolerable voltages based on body impedances not exceeded for 5% of the population, as given in DD IEC/TS 604791:2005, Table 1 (Column 2) rather than the 50% values (Column 3). The UK obtained a variation to the new CENELEC and IEC standards which has been r

16、ecognized in the foreword of BS EN 619361:2010 and BS EN 50522:2010, Annex Q (ADeviations). Hence, these documents specify the required difference in approach to earthing design in the UK, based on the 5 % body impedance values. The new UK tolerable touch voltage figures are given in BS EN 50522, Na
