Analysis of three-phase networks in disturbed operating conditions using symmetrical components

The dimensioning of an installation and the equipment to be used, the settings for the protection devices, and the analysis of electrical phenomena often require calculation of the currents and voltages in electrical networks.

The purpose of this “Cahier Technique” is to set out a simple method of calculating all these parameters in three-phase networks subject to disturbance using the symmetrical components method, and to provide specific application examples.
