Questa Parte 8 della serie di Norme EN/IEC 60099 riguarda gli scaricatori ad ossido metallico con spinterometri esterni in serie (EGLA) posti a protezione delle catene di isolatori delle linee aeree di trasmissione e distribuzione unicamente dalle scariche atmosferiche. Rispetto alla precedente, in questa seconda edizione, oltre alla introduzione di nuovi termini e alla conversione di alcune note in requisiti normativi, la prova di capacità di scarica atmosferica è stata riscritta e rinominata prova di verifica del grado di trasferimento di carica ripetitiva Qrs, per riflettere le modifiche introdotte dalla Norma EN/IEC 60099-4 Ed.3 (2014). In aggiunta alle prove per valutare le prestazioni dei resistori ad ossido metallico, sono state introdotte le procedure per determinare le prestazioni degli spinterometri esterni in serie (EGLA). Infine, sono state colmate alcune lacune, in particolare prescrivendo una prova di tensione da radio interferenza (RIV) e un metodo per determinare la costante di tempo termica del varistore dell’EGLA.
La Norma in oggetto sostituisce completamente la Norma CEI EN 60099-8:2012-04, che rimane applicabile fino al 19-12-2020.
Questa Norma viene pubblicata dal CEI nella sola lingua inglese in quanto particolarmente mirata a settori specialistici.
La presente Norma recepisce il testo originale inglese della Pubblicazione IEC.

ICS

International Classification for Standards (ICS) is an international classification system for technical standards.

The ICS is a hierarchical classification organized on three levels.

Level 1 covers the main fields of activity in standardization, e.g. road vehicle engineering, agriculture, metallurgy.

Each field has a two-digit notation, e.g.

  43    Road Vehicle Engineering

The main fields are subdivided into groups (level 2). The notation of a group consists of the field notation and a three-digit group number, separated by a point, e.g.

  43.040    Road vehicle systems

Some groups are further divided into sub-groups (level 3). The notation of a sub-group consists of the group notation and a two-digit number, separated by a point, e.g.

  43.040.20 Lighting, signaling and warning devices

You can identify the ICS code of your interest by typing the code or a keywordword in the dropdown ICS field, and by selecting one of the filtered results.

Search also in the summary/description of the standard

By flagging this control, the search for keywords will not be limited to the Standard Number and Title fields, but will also be performed in the Abstract of the standard.

This way, you will get more results.

You should use this option when you can not find the desired result with the standard approach and it is necessary to extend the scope of the search: by increasing the number of results, you will increase the number of non-relevant elements, as well.
