Construction. - A number of similar circuit breaking units are used in series per phase.", "Image ImageDescription": "- Up to 12 breaks per phase are used for the highest breaking capacities at 400kV. - Up to 24 breaks per phase are used for 750kV. - The number of breaks is dictated by the limitation of testing station capacity rather than. interrupting capacity possible per break. - The tank is permanently charged with compressed gas and encloses two breaks. connected in series, the tank being tied electrically to the mid-point potential between. breaks. - For 400kV, if twelve breaks are required, then. two live tanks can be supported by a single. porcelain insulator, making three support. insulators in all phase. 6/34.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
