Device for Protection Against Transient and Temporary Overvoltage Including Limitation of the Specific Energy

An arrangement is presented which ensures protection against transient and line frequency overvoltage and limits the load on the consumer to a minimum even in case of transient currents. The arrangement consists of a special arrester in the shunt circuit, a fast switch in the series circuit as well as a control and measuring device. The design, mode of operation and parameters of the components of the arrangement are described based on different loads. The protective effect is discussed
