Patent attributes
A switching apparatus comprises: a first current-conductive branch (12) including a first switching element (24), the first switching element (24) configured to be switchable to selectively permit and block a flow of current in the first current-conductive branch (12); a second current-conductive branch (14) including a second switching element (32), the second switching element (32) configured to be switchable to selectively permit and block a flow of current in the second current-conductive branch (14); and first and second terminals (18,20) for connection, in use, to an electrical network (22), wherein the first and second current-conductive branches (12,14) extend between the first and second terminals (18,20), wherein the first current-conductive branch (12) further includes an energy storage element electrically coupled to the second switching element (32) so that the energy storage element is configured as a power source for enabling the operation of the second switching element (32), and the first switching element (24) is configured to be switchable to selectively direct a current flowing in the first current-conductive branch (12) to flow through the energy storage element so as to store energy in the energy storage element.
