Handling a voltage fluctuation problem
Voltage quality - Fluctuations and flicker

The main diagnostic steps are as follows:

• identifying disruptors ;

• calculation of the emission of each disturbance at the common coupling point ;

• determining compatibility with recommendations ;

• identification of loads causing disturbances ;

• study of the effectiveness of each solution ;

• prioritization of solutions in order of effectiveness.

Finding the common coupling point is an important part of the problem. In this case, it is important to take into account possible changes in the network. Two cases have recently been encountered...
