A low-cost high-performance MV switchgear for use in remote-controlled MV/LV substations: First results of Enel distribuzione experimentation

To achieve the quality of service objectives set by the Italian energy market regulation authority, Enel implemented an efficient and highly effective automatic fault detection system in its MV (Medium Voltage) network. Its performance and upgrade possibilities are influenced and sometimes limited by the characteristics of the switchgears currently installed in the network. To overcome these limits, different network components are needed, hence the specification, test and adoption of a new high performance MV switchgear. These new switchgears have been installed on Enel network since the beginning of the year 2008 and all the feedback coming from the field are encouraging and completely in line with Enel first expectations.
