SF6-alternatives monitorand record for Hitachi

Despite the growing number of demonstration projects for SF6 free MV and HV equipment, many industry experts continue to argue there are an insufficient number of SF6 alternatives for certain applications and the track records for the available alternatives are too limited to ban SF6. Because of its performance record
