Pribor za močnostne transformatorje in dušilke - 4. del: Osnovni pribor (ozemljitveni priključek, naprave za polnjenje in praznjenje, termometrski žep, kolesni sestav)

Standard EN 50216-4 določa osnovni pribor za transformatorje/dušilke, na primer:
− termometrski žepi, ki se uporabljajo za transformatorje, potopljene v tekočino,
− ozemljitveni priključki, ki se uporabljajo za transformatorje, potopljene v tekočino, in transformatorje suhega tipa,
− odtočni čepi, ki se uporabljajo za distribucijske transformatorje, potopljene v tekočino,
− odprtine za polnjenje, ki se uporabljajo za distribucijske transformatorje, potopljene v tekočino,
− valji, izbira in razdalja, ki se uporabljajo za transformatorje, potopljene v tekočino, in transformatorje suhega tipa.
Po dogovoru med kupcem in proizvajalcem je lahko ta del standarda EN 50216 Series še vedno veljaven v celoti ali delno za velike močnostne transformatorje ali posebne transformatorje.
