Draft Interpretation Sheet Annex G
Background
Clause G.2 states that:
“… linear sources of power shall have their maximum voltage within the limit curve for linear
source from the applicable diagram from Figure G.2 or Figure G.3.”
However, the clause does not state the corresponding current at which the maximum voltage
of the linear source should be drawn in the applicable diagram.
Question:
What is the correct point to apply diagrams from Figure G.2 or Figure G.3 for linear sources?
