Insulating liquids – Test method for detection of potentially corrosive sulphur in used and unused insulating oil

La presente Norma fornisce un metodo per la determinazione dello zolfo potenzialmente corrosivo eventualmente presente in oli dielettrici usati e nuovi.

Guasti recenti verificatisi a carico di trasformatori e reattori elettrici a causa della presenza di zolfo corrosivo negli oli isolanti sono stati causati dalla formazione di un deposito di solfuro di rame sulla superficie della carta che avvolge i conduttori di rame. La crescita di solfuro di rame sui conduttori di rame metallico può causare la formazione di particolato all’interno dell’olio, che agisce come punto di innesco per scariche elettriche conducendo quindi a guasti.

Il metodo proposto fa pertanto uso di un conduttore di rame avvolto da uno strato di carta immerso in olio riscaldato, del quale si valuta la capacità di produrre solfuro di rame e trasferirlo allo strato di carta.
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.

What People Are Saying

Thanks to the StandardsClub customer service team for helping me find the ASME BPVC-2023 SET I was looking for in a high-quality PDF version. Their assistance was excellent, and the document quality exceeded my expectations!

This standard document is very detailed, covering all relevant technical points, and provides comprehensive guidance for my project. The ANSI/NEMA Z535 SET was exactly what I needed, and I am very satisfied with the quality!

The purchasing process was straightforward, the price was very competitive, and the download was quick. The Tissue Engineering Standards Addressing Product Quality and Characterization Package was of excellent quality and provided all the information I needed. Definitely a great value for the price!
