Protection against lightning - Thunderstorm warning systems
IEC 62793:2016(E) describes the characteristics of thunderstorm warning systems and evaluation of the usefulness of lightning real time data and/or storm electrification data in order to implement lightning hazard preventive measures. This standard provides the basic requirements for sensors and networks collecting accurate data of the relevant parameters, giving real-time information of lightning tracks and range. It describes the application of the data collected by these sensors and networks in the form of warnings and historical data. This standard applies to the use of information from thunderstorm warning systems (systems or equipment providing real-time information) on atmospheric electric activity in order to monitor preventive measures.
Blitzschutz - Gewitterwarnsysteme
Protection contre la foudre - Dispositifs de détection d'orage
L'IEC 62793:2016 décrit les caractéristiques des systèmes d'alerte aux orages, ainsi que l'évaluation du degré d'utilité des données en temps réel relatives aux éclairs et/ou à l'électrisation des orages, afin de mettre en œuvre des mesures préventives contre les dangers de la foudre. La présente norme indique les exigences fondamentales applicables aux capteurs et aux réseaux de collecte de données précises pour les paramètres pertinents, qui fournissent des informations en temps réel sur la trajectoire et l'amplitude d'un éclair. Elle décrit les applications des données collectées par ces capteurs et ces réseaux sous la forme d'alertes et de données historiques. La présente norme s'applique à l'usage des informations recueillies par les systèmes d'alerte aux orages (systèmes ou équipements fournissant des informations en temps réel) sur l'activité électrique atmosphérique, à des fins de surveillance des mesures préventives. La présente version bilingue (2018-11) correspond à la version anglaise monolingue publiée en 2016-05. La version française de cette norme n'a pas été soumise au vote.
Zaščita pred delovanjem strele - Sistemi za opozarjanje pred nevihtami
Ta mednarodni standard opisuje značilnosti sistemov za opozarjanje pred nevihtami ter oceno uporabnosti podatkov o strelah v realnem času in/ali podatkov o elektrifikaciji neviht za izvajanje preventivnih ukrepov proti nevarnosti zaradi strele. Ta standard določa osnovne zahteve za tipala in omrežja, ki zbirajo natančne podatke o ustreznih parametrih ter v realnem času zagotavljajo podatke o sledenju strelam in njihovem obsegu. Opisuje uporabo podatkov, ki jih zberejo ta tipala in omrežja v obliki opozoril in zgodovinskih podatkov.
Ta standard se uporablja za uporabo podatkov sistemov za opozarjanje pred nevihtami (sistemi ali oprema, ki zagotavljajo podatke v realnem času) o električni dejavnosti ozračja za spremljanje preventivnih ukrepov.
Ta standard zajema:
• splošen opis razpoložljivih sistemov za opozarjanje pred nevarnostjo elektrifikacije zaradi strel in neviht;
• klasifikacijo in lastnosti naprav za zaznavanje neviht;
• smernice za metode opozarjanja;
• postopek za ugotavljanje koristnosti podatkov o nevihtah;
• nekaj informativnih primerov možnih preventivnih ukrepov.
Naslednji vidiki ne spadajo na področje uporabe tega standarda:
a) sistemi za zaščito pred delovanjem strele; ti sistemi so zajeti v skupini standardov IEC 62305;
b) drugi pojavi, povezani z nevihtami, kot so dež, toča, veter;
c) tehnike odkrivanja neviht s sateliti in z radarji.
Spodaj je naveden neizčrpen seznam situacij, za katere se lahko uporabi ta standard:
• ljudje na prostem, ki se ukvarjajo z dejavnostmi, kot so vzdrževalna dela, delo, šport, tekmovanja, kmetijstvo in ribištvo ali situacije, ko se zbere večja množica ljudi;
• vetrne elektrarne, veliki sistemi za zbiranje sončne energije, električni vodi;
• zagotavljanje varstva in zdravja pri delu;
• občutljiva oprema, kot so računalniški sistemi, intervencijski sistemi, alarmi in varnostna oprema;
• operativni in industrijski postopki;
• shranjevanje, predelava in prevoz nevarnih snovi (npr. vnetljivih, radioaktivnih, strupenih in eksplozivnih snovi);
• določena okolja ali dejavnosti, pri katerih obstaja velika nevarnost elektrostatičnih razelektritev (npr. vesoljska in letalska plovila);
• postopki, pri katerih je zelo pomembno neprekinjeno delovanje osnovnih storitev (npr. telekomunikacije, proizvodnja, prenos in distribucija energije, sanitarne storitve in intervencijske storitve);
• infrastruktura: pristanišča, letališča, železnice, avtoceste in žičnice.
