Abstract

The method involves increasingly generating current on grid-bound transfer paths e.g. cables (6, 8, 8.1, 9.1, 9.2), till reaching a predetermined value in a time-dependent manner using an end module (10). A voltage is measured at ends of the grid-bound transfer paths using the end module. The measured voltage is compared with a reference value using the end module, where a bus coupler (4) is provided for transferring the end module to a check mode. An error message is generated during shortfall of the reference value. An independent claim is also included for a hazard alert system with a control center part, where a bus coupler is connected over a communication bus at the center part.
