The issues poor power quality causes
|
Shorter equipment life
Plant and equipment are designed to operate in a system with good power quality and so power quality issues can cause overheating, damage to sensitive equipment or equipment failure. Outages and shutdowns With less equipment failure, comes less outages and shutdowns. Poor operational efficiency When power factor and harmonics issues are corrected, plant and equipment can use the full power available to them and operate more efficiently. Less outages and shutdowns also increase operational efficiency. Utility penalties Facilities with poor power factor or excess harmonics are often charged penalties by their utility, as the poor power factor and harmonics effect the network and others connected to the network. |
How active harmonic filters work
|
Active harmonic filters recognise which harmonics are ‘out-of-balance’ and inject inverse currents to cancel out this unbalance.
Active harmonic filters need to be matched to your electrical system. We have a wide variety available – ask our team which one will be suitable for your system. |
