ELEVATED HARMONICS LEVELS
We prevented damaging downtime caused by elevated harmonics levels to a large pharmaceutical plant in the West of Ireland. The plant, which manufactures market-leading medicines, had issues with harmonics and needed to ensure reliability of plant. As a result of our work, harmonic currents fell from 55% to 16% at the facility.

This pharmaceutical facility had recently introduced a new production process which required a reliable, mission critical electrical supply. The company had experienced previous downtime due to malfunctioning electrical systems. A full evaluation was required to ensure that the facility’s electrical distribution network was functioning as required and could support the new pharmaceutical production equipment.
HOW WE HELPED
After conducting an extensive power quality metering assessment with advanced portable devices we identified vulnerable points on the network. The assessment highlighted significant breaches of the voltage harmonic limits for controlled and sensitive equipment as stipulated by the IEC 61000-2-4 standard. We modelled the facility’s electrical distribution network using our specialist software analysis programs to size a filtering solution that would mitigate any harmonic issues.
We supplied and commissioned multiple active harmonic filters at the facility based on our analytical results. Harmonic currents fell from 55% to 16%, thus lowering the level of voltage harmonic distortion, maintaining it within the IEC 61000-2-4 limits and preventing future failures of critical devices, such as PLCs and controls.
This large pharmaceutical plant produce market leading medicines for export throughout the world. They employ almost 30,000 people worldwide and have a global turnover of $20bn in 2014.
