Misurazione di tensione, corrente e temperatura per l’alimentazione di corrente DC

Per la misurazione precisa e affidabile di tensione e corrente in impianti a corrente continua, Knick fornisce da decenni trasmettitori isolati galvanicamente. In questo periodo l’azienda si è sviluppata fino a diventare leader sul mercato in questo settore. Knick è pertanto anche il primo referente per i fornitori e i gestori di impianti a corrente continua quando si tratta di vincere sfide tecniche particolari, ad es. il monitoraggio dell’usura per una manutenzione predittiva.

Perché Knick?
I dispositivi di protezione nelle sottostazioni elettriche devono misurare corrente e tensione per eseguire algoritmi per il riconoscimento di cortocircuiti. Questo richiede trasmettitori ad alta tensione che misurano con rapidità e precisione e resistono al tempo stesso a carichi elevati. Devono resistere a tensioni comprese tra 750 e 3000 V DC e anche a sovratensioni temporanee, ad esempio durante il recupero di energia nei treni in frenata. In queste applicazioni ad alta tensione la protezione delle persone e dei dispositivi è di importanza fondamentale. Pertanto, la forte separazione galvanica dei dispositivi Knick è un aspetto importante nella scelta dei trasmettitori.
