"This project was a new build, yet this did not prevent the harmonic issues from occurring. Our extensive power quality and harmonic survey of the electrical distribution network identified a number of issues. Using this information we could then select, supply and commission active harmonic filters needed to correct the problems."

Harmonic Mitigation - Glanbia
We have increased reliability and largely reduced downtime to this large food plant in the South-East of Ireland. The plant, which manufactures nutritions, had issues with harmonics and needed to ensure reliability of plant. As a result of Premium Power’s work, total harmonic voltage distortion fell from 6.5% to 3.5% at the facility.

Due to high quantity of variable speed drives installed across the network for energy efficiency purposes, an elevated level of harmonic currents and voltage was being constantly recorded throughout the plant. It was identified very early that those abnormal harmonic levels will have a negative impact on the performance of the facility. A full evaluation was required to ensure that the electrical distribution network will function as required and could reliably support the new milk processing production equipment.
We supplied and commissioned multiple active harmonic filters based on our analytical results. Total harmonic voltage distortion fell from 6.5% to 3.5%, maintaining it within the IEC 61000-2-4 limits, preventing future failures of critical devices, such as PLCs and controls, reducing the energy losses due to excessive currents and extending lifespan of mission critical power equipment.
