用于确定电压中断的原因的方法，辅助单元及电力系统
摘要：
在用于确定断路器负载端的电压中断的原因的方法中，负载端的电压中断对应于断路器的断开或对应于在断路器输入端处的电压降低于第一参考电压值，断路器在断开位置能够截断电流的流动。辅助单元包括能够测量在电导体中流动的电流的强度的至少一个电流传感器以及能够检测断路器负载端的电压中断的第一检测装置。所述方法包括以下步骤：通过电流传感器测量在电导体中流动的电流的强度(102)，经由第一检测装置检测断路器负载端的电压中断(117)。所述方法还包括以下步骤：通过辅助单元并根据用电流传感器测量的强度来确定断路器负载端检测的电压中断的原因(120，122，124，126，128，130)，所述原因优选地选自这样的组：电过载，短路和电压降。
摘要（英）：

In this method, the voltage outage load-side is an opening of the circuit breaker, and the circuit breaker is able to interrupt the flow of electric current in an electric connection including an electric conductor. The auxiliary unit comprises a current sensor for measuring the intensity of the current flowing in the electric conductor and a first detection means for detecting the voltage outage load-side from the circuit breaker. The method comprises the following steps: measuring the intensity of the current flowing in the electric conductor, detecting the voltage outage load-side from the electric circuit breaker, determining a cause of the detected voltage outage load-side from the circuit breaker, said cause being selected from the group consisting in: an electric overload, a short-circuit and a voltage drop.
