Device and method for electrical charge detection and electrical apparatus equipped with such a device

The charge detector is connected to an isolated electric line, and a variable voltage is injected into the line to cause a variation in impedance. The impedance variation is measured (30) and variation (dZ) determined. The variation is processed (31, 35) to determine whether the impedance change cor...

Summary:The charge detector is connected to an isolated electric line, and a variable voltage is injected into the line to cause a variation in impedance. The impedance variation is measured (30) and variation (dZ) determined. The variation is processed (31, 35) to determine whether the impedance change corresponds to a differential fault (32) or contact with a human body (34).
