Grid transient measurements
Grid transients occur when switching actions take place, but they can also be caused by lightning. An understanding of the processes and quantification of the maximum voltages and currents that occur in these cases is a key factor in the coordination of insulation (dimensioning of equipment insulation and equipment to protect against excess voltage). FKH offers measurements of transient events of all types.
Apart from the problems caused by fast grid transients, other important issues relate to low-frequency phenomena such as resonance and ferroresonance events that can cause thermal overloads of grid components as well as insulation overloads. FKH regularly carries out investigations of disruptive events such as these.
