Protective circut for a breaker gap

摘要

The invention relates to a protective circuit for a breaker gap (2), said gap being used to connect a load voltage (UL) to a load (1). The circuit is characterized in that a voltage detection circuit (3) is connected to a detection point (4) on the input side and a detection point on the output side of the breaker gap (2), via detection resistances (R1) said voltage detection circuit (3) being connected to the detection points (4) at high-resistance but in a permanently galvanized manner.
