Detector determining switched on condition of electric user loads at house mains

摘要

The detector for identifying the switched on condition of electrical user loads connected to a domestic current mains includes a comparator (5). The comparator monitors the actual characteristic value (IK) of the current flowing in the domestic current mains. The comparator activated across a switch (8) compares the actual characteristic value (IK) with a fed in base load value (GW). The base load value (GW) represents the current take up of continuously switched on and cyclically or intermittently self switched on user loads. The comparator (5) activates an alarm signal if the actual characteristic value (IK) exceeds the base load value (GW).
