Claim:
1. A method for monitoring a high-voltage arrangement, the method comprising: impressing a current onto a current loop, wherein the current loop runs through a multiplicity of elements, to be monitored, of the high-voltage arrangement, wherein a change in a state of at least one of the elements to be monitored leads to an interruption in the current loop; sensing voltages at at least three points on the current loop; detecting an interruption in the current loop as a function of the voltages; interrupting a high-voltage supply of the high-voltage arrangement and discharging the high-voltage arrangement when an interruption is detected; and determining the location of the interruption as a function of the voltages, wherein the sensing of voltages at at least three points on the current loop comprises sensing a first voltage at a start of the current loop, and sensing a second voltage at an end of the current loop, wherein the detection of the interruption is the current loop is performed only on the basis of the first voltage and the second voltage, and wherein the monitoring is performed using a monitoring apparatus which is arranged outside the high-voltage arrangement.
