Harmonic management

Disturbances caused by harmonics
Harmonics flowing in distribution networks downgrade the quality of electrical power.
This can have a number of negative effects:
Electrical Installation guideOverloads on distribution networks due to the increase in rms current
Electrical Installation guideOverloads in neutral conductors due to the cumulative increase in third-order harmonics created by single-phase loads
Electrical Installation guideOverloads, vibration and premature ageing of generators, transformers and motors as well as increased transformer hum
Electrical Installation guideOverloads and premature ageing of power-factor correction capacitors
Electrical Installation guideDistortion of the supply voltage that can disturb sensitive loads
Electrical Installation guideDisturbances in communication networks and on telephone lines
