3. Definitions For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dictionary Online should be consulted for terms not defined in this clause. 4 conductor: A metallic substance that allows a current of electricity to pass continuously along it. As used in this standard, a conductor includes cable (wire), rods (electrodes), and metallic structures. conductor combination: The various conductors that are joined by a connection. connection: A metallic device of suitable electrical conductance and mechanical strength used to join conductors. connection thermal capacity: The ability of a connection to withstand the amount of current required to produce a specified temperature on the control conductor without increasing the resistance of the connection beyond that specified in this standard. control conductor: The conductor that is utilized to measure equivalent changes in temperature, size, etc., that are occurring in at least one of the conductors joined by the connection under test. current loop cycle: The combination of conductors and connections that carries the current of the circuit under test. equalizer: A device to provide equipotential planes for resistance measurements. grid system: A system consisting of interconnected bare conductors buried in the earth or in concrete to provide a common ground for electrical devices and metallic structures. permanent connection: A grounding connection that will retain its electrical and mechanical integrity for the design life of the conductor within limits established by this standard. 4. Qualification tests For qualification test sequence, refer to Annex D. Qualifications tests shall be performed for each family of connections, for example: (cable to cable straight connection, tap connection, cross connection), (cable to ground rod connection), (cable to lug connection), and (cable to structure connection). Qualification tests shall be performed for each style of connection.
