High-voltage switchgear and controlgear are devices which are used both to de-energize equipment to allow work to be conducted and also to clear faults downstream in an electric power system.
PD IEC/TR 62271-301 is a technical report which applies to high-voltage switchgear and controlgear such as circuit-breakers, disconnectors and switches. However, its application to other equipment is not excluded. No coordination between dimensions and the rated normal current can be given.
PD IEC/TR 62271-301 on high-voltage switchgear and controlgearis helpful for:
Having access to reliable guidelines is essential to prepare and use quality high-voltage switchgear and controlgear.
PD IEC/TR 62271-301 provides manufacturers with the vital requirements, specifications and measurements which allows them to manufacture and test standardized high-voltage switchgear and controlgear effectively.
