Elektrische Schutzeinrichtung

The device for protecting against contact currents consists of an isolation transformer (TR) and an insulation monitor (IU). The protected person (P) is connected via a resistor (R3) to the centre tapping of a potential divider (R1,R2) which is connected to the transformer secondary. A current chang...

Beschreibung
Zusammenfassung:	The device for protecting against contact currents consists of an isolation transformer (TR) and an insulation monitor (IU). The protected person (P) is connected via a resistor (R3) to the centre tapping of a potential divider (R1,R2) which is connected to the transformer secondary. A current change in the three resistors caused by a single or double insulation failure triggers a warning signal and/or the switching off of the device and/or the activation of a redundant protection device. ADVANTAGE - Ensures safe operation of one or more electrical devices irrespective of local safety measures and ambient conditions.
