This International Standard specifies the rules for signs and reference directions and reference polarities for electric currents and voltages in electric networks.
In Clauses 3 to 10, the time dependence is arbitrary. It is assumed that the wavelength of the highest frequency involved is larger than the largest distance between two points of the network; processes are considered to be quasi-static. Clause 11 specifies the rules and recommendations for complex notation.
