DEVICE AND METHOD FOR DETERMINING A GROUND CONDUCTOR RESISTANCE FOR A CHARGING DEVICE

The invention relates to the measurement of a ground conductor resistance for a charging device, wherein the charging device is configured to have a phase conductor (L), a neutral conductor (N), a ground conductor (PE) and a current transformer (W). The phase conductor (L), the neutral conductor (N) and the ground conductor (PE) are guided through the current transformer (W), so that the ground conductor (PE) forms a winding around the current transformer (W). The phase conductor (L) is connected to the ground conductor (PE) via a first resistor (R) by means of a first connection (V1), whereinthe two connection points of the two conductors are arranged on different sides of the transducer (W). 本发明涉及种对于充电装置的接地线电阻的测量，其中，充电装置构造为具有相线(L)、中性线(N)、接地线(PE)以及电流互感器(W)。在此，相线(L)、中性线(N)和接地线(PE)被引导通过电流互感器(W)，从而接地线(PE)形成围绕电流互感器(W)的绕组。相线(L)借助第连接(V1)经由第电阻(R)与接地线(PE)连接，其中这两条导线的两个连接点被布置在互感器(W)的不同侧上。
