Abstract

A breather device (1) for dehumidifying air to be supplied into an expansion vessel (103) of a power electrical apparatus (100), said breather device comprising an air demoisturizer unit (2) including one or more tanks (2) having an internal volume (20) accommodating a moisture absorbing substance and being adapted to be in fluid-dynamic communication with the external environment and with said expansion vessel.The breather device comprises one or more capacitive electric arrangements (10) accommodated in said one or more tanks (2).Each capacitive electric arrangement comprises first and second electrodes (11, 12) arranged spaced one from another in the internal volume (20) of a corresponding tank (2) and a quantity of said moisture absorbing substance between said first and second electrodes.The breather device breather device further comprises or is operatively coupleable with a detection device (50) electrically connectable with the capacitive electric arrangement of a tank and adapted to provide at least first measurement data (C) indicative of the equivalent capacitance of said capacitive electric arrangement.
