4. Propagation

It is necessary to be able to calculate harmonic voltage levels at every point on a power network to check compliance with limit levels 7 , as well as the harmonic currents flowing through each element in order to determine its sizing or detect any overloading.

As a general rule, harmonic currents propagate with little attenuation from low-voltage networks to high-voltage networks (there is an exception for ranks multiple of...

Technical and economic aspects

In the introductory article , it is shown that equipment connected to a network must, on the one hand, not "emit too much" disturbance and, on the other hand, must not be "too sensitive" to this same disturbance. While simple to express, this dual concept is more difficult to implement in the field. Indeed, for a particular piece of equipment, reducing its emission of disturbance and/or...
