适用范围：This International Standard deals with transformations from original quantities into modalquantities for the widely used three-phase a.c. systems in the field of electric powerengineering.The examination of operating conditions and transient phenomena in three-phase a.c.systems becomes more difficult by the resistive, inductive or capacitive coupling between thephase elements and line conductors. Calculation and description of these phenomena inthree-phase a.c. systems are easier if the quantities of the coupled phase elements and lineconductors are transformed into modal quantities. The calculation becomes very easy if thetransformation leads to decoupled modal systems. The original impedance and admittancematrices are transformed to modal impedance and admittance matrices. In the case ofdecoupling of the modal quantities, the modal impedance and admittance matrices becomediagonal matrices.
