Harmonic currents result in power that can't be used and which also takes up electrical system capacity. Large quantities of harmonics can lead to malfunctioning of the system that results in downtime and increase of the operating costs.
Harmonics are a problem for a wide number of business sectors and the costs are high and
rising as the number of disturbances are increasing and modern production equipment is becoming more sensitive to these disturbances.
Every consumer of Electricity Board at 415 V should possess, who experience harmonic related issues such as:
- Overload
- Malfunction in control circuitry
- Heavy application of electronic drives
- Nuisance Tripping & mis-coordination of relays
- Over heating of system components
Passive harmonic filters operate mainly on a fixed or stepped basis using passive elements. All these solutions suffer from the same drawbacks – they add losses, are installation specific and have no ability to adapt to or follow dynamic load changes.
The Active harmonic filter eliminate loss creating behaviors such as harmonics, flicker, voltage variations, resonances and reactive energy using a highly dynamic, step less digitally controlled compensation and filtering approach. By continuously monitoring the network and injecting exactly the right amount of compensation current – at exactly the right time – the most efficient and accurate solution to any power quality problem can be achieved.
This approach enables the current waveform to be restored instantaneously, the current consumption to be lowered and changes in load or installation conditions to be fully compensated at all times
For modern facilities, where load and network change constantly, this solution not only represents an opportunity, but is a necessity.
