Protection against lightning - Thunderstorm warning systems
This European Standard provides the basic requirements of sensors and networks collecting accurate data of the relevant parameters informing in real-time about lightning tracking and range. It describes the application of the data collected by these sensors and networks in the form of warnings and historical data. This European Standard applies to the use of information from thunderstorm warning systems (which are systems or equipment which provide real-time information) on atmospheric electrical activity in order to monitor for preventive means. The scope of this document is providing: – a general description of the available lightning and storm electrification hazard warning systems; – a classification of thunderstorm detection devices and properties; – guidelines for alarming methods; – a procedure to determine the thunderstorm information necessity; – some examples of possible preventive actions (only for information). A non-exhaustive list of activities to which this European Standard might apply is given below: – people in open areas: maintenance people, labour, sports or other open-air activities, competitions, crowded events, agricultural activities, farms and fisheries; – wind farms, larger solar power systems, power lines, etc.; – occupational health and safety prevention; – safeguard sensitive equipment: computer systems, electric or electronic systems, emergency systems, alarms and safety; – prevention of losses in operations and industrial processes; – prevention of serious accidents involving dangerous substances (e.g. flammable, radioactive, toxic, and explosive); – prevention in determined environments or activities with special danger of electrostatic discharges (e.g. space and flight vehicle operations); – operations in which the continuity of the basic services is needed to be guaranteed (e.g. telecommunications, the generation, transport and distribution of energy, sanitary services and emergency services); – infrastructures: ports, airports, railroads, motorways and cableways; – civil defence of the environment: forest fires, land slide and floods; – managing traffic (e.g. airplanes.) or wide networks (e.g. power lines, telecommunication lines) may also benefits from having early detection of thunderstorms. The following enumerated aspects are outside of this European Standard: a) lightning protection which is covered in their corresponding European and National standards and regulations; b) other thunderstorm related phenomena such as rain, hail, wind, etc.; c) satellite and radar thunderstorm detection techniques; d) this European Standard does not address any details on lightning and/or storm electrification hazard preventive actions.
Blitzschutz - Gewitterwarnsysteme
Diese Europäische Norm liefert die technischen Anforderungen an Messempfänger und Messnetze, die genaue Daten der zugehörigen Parameter sammeln, um in Echtzeit über Gewitterzugrichtung und -zellen zu informieren. Sie beschreibt die Anwendung der von diesen Messempfängern und Messnetzen gesammelten Daten in Form von Gefahrenmeldungen und historischen Daten. Diese Europäische Norm gilt für die Nutzung von Informationen aus Systemen zur Gewitterortung (das sind Systeme oder Geräte, die Echtzeitinformationen liefern) zur Beobachtung von atmosphärischen, elektrischen Aktivitäten, zum Zweck vorbeugender Maßnahmen. Der Anwendungsbereich dieses Dokumentes umfasst: – eine allgemeine Beschreibung der verfügbaren Warnsysteme für Blitz- und Gewitter¬elektrizitäts-gefährdung; – eine Klassifizierung der Gewitterortungssysteme und deren Eigenschaften; – Leitfäden für die Alarmierung; – eine Verfahrensweise zur Bestimmung der Notwendigkeit von Gewitterinformationen; – einige Beispiele möglicher, vorbeugender Maßnahmen (nur informativ). Nachfolgend ist eine nicht vollständige Liste von Aktivitäten, auf die diese Europäische Norm angewendet werden könnte, angegeben: – Menschen im Freien: Servicetechniker, Arbeiten, Sport oder andere Freiluftaktivitäten, Wettkämpfe, stark besuchte Veranstaltungen, landwirtschaftliche Tätigkeiten, Bauernhöfe und Fischereien; – Windenergieanlagen, größere Solarenergiefelder, Stromversorgungsleitungen, etc.; – berufsbedingte Gesundheits- und Sicherheitsvorsorge; – Schutzeinrichtungen für empfindliche Ausrüstungen: Computersysteme, elektrische oder elektronische Systeme, Notfalleinrichtungen, Alarm- und Sicherheitssysteme; – Verhindern von Verlusten im Betrieb und in industriellen Prozessen; – Verhindern von schweren Unfällen mit gefährlichen Stoffen (brennbar, radioaktiv, giftig oder explosiv); – Vorbeugen in bestimmter Umgebung oder bei Tätigkeiten mit besonderer Gefahr elektrostatischer Entladungen (Raum- und Luftfahrt); – Abläufe, bei denen die Zuverlässigkeit von Grunddiensten garantiert werden muss: Telekommunikation, Energieerzeugung, -transport und -verteilung, Gesundheits- und Notfalldienste; – Infrastrukturen: Häfen, Flughäfen, Schienenverkehr, Autobahnen und Seilbahnen; – öffentlicher Schutz der Umwelt: Waldbrände, Geländeabschwemmungen und Überschwemmungen; – Verkehrsleitsysteme (Flugzeuge, etc) oder ausgedehnte Netze (Stromversorgungsleitungen, Telekommunikationsleitungen) können ebenfalls Vorteile aus der frühzeitigen Ortung von Gewittern ziehen. Die im Folgenden aufgezählten Punkte sind nicht Bestandteil dieser Europäischen Norm: a) Blitzschutz, der in entsprechenden Europäischen und Nationalen Normen und Richtlinien enthalten ist; b) andere meteorologische, blitzbezogene Erscheinungen wie Regen, Hagel, Wind, etc.; c) satelliten- und radargestützte Gewitterortungstechniken; diese Europäische Norm beschäftigt sich nicht mit irgendwelchen Einzelheiten zu vorbeugenden Maßnahmen bei Blitz- und/oder Gewitterelektrizitätsgefährdung.
Protection contre la foudre - Dispositif de détection d'orage
Zaščita pred delovanjem strele - Naprave za zaznavanje neviht
Ta evropski standard podaja osnovne zahteve za senzorje in omrežja, ki zbirajo točne podatke o ustreznih parametrih, ki realnočasovno obveščajo o sledenju in razponu pojava strele. Opisuje uporabo podatkov, zbranih s temi senzorji in omrežji, v obliki opozoril in zgodovinskih podatkov. Ta evropski standard velja za uporabo informacij iz opozorilnega sistema pred nevihtami (to so sistemi ali oprema, ki zagotavljajo realnočasovne informacije) o atmosferski električni dejavnosti, da se zagotovi spremljanje za preventivna sredstva. Področje uporabe tega standarda zagotavlja: - splošni opis razpoložljivih opozorilnih sistemov o elektrifikacijskih nevarnostih pojava strele in nevihte; - klasifikacijo in lastnosti naprav za zaznavanje neviht; – smernice za metode alarmiranja; postopek določevanja uporabnosti informacij o nevihti; – nekaj primerov mogočega preventivnega delovanja (samo informativno).
