Harmonic Filters

By installing harmonic filters several benefits are obtained:

• Higher power factor, improved voltage stability and network losses
• Filtering of harmonics in the system
• Avoidance of resonance problems and amplification of electrical disturbances.

• Increased losses, e.g. machines will operate at increased temperature and can be overheated
• Resonance problems between the inductive and capacitive parts of the power network
• Malfunctioning of control systems since electronic meters, relays, etc. are matched to the fundamental frequency
• Overloading of capacitors, leading to malfunctioning and premature aging
• Interference with telecommunications and computers
• Disturbances in ripple control systems
• High currents in neutral conductors.
