Abstract

La présente invention est une manière unique de mesurer électroniquement une situation de PEN ouverte dans un système à phases multiples sans référence à la terre mère. Si la tension flottante devient dangereuse, le dispositif déconnecte le circuit, évitant une situation potentiellement dangereuse de se développer.
