Unplanned paper machine downtime is a thing of the past. Through targeted Power Quality diagnostics and the implementation of active filtering, HyTEPS guarantees continuity in the production process of this world leader.
In the complex electrical installation of Sappi Maastricht B.V., a world leader in coated graphic paper, downtime is not an option. Yet the company faced a critical challenge: the analogue-digital cards in the process control system failed in quick succession. This resulted in repeated breakdowns of the paper machine.
Such outages are extremely costly and create uncertainty on the shop floor. The source of the problem initially remained unclear, leading to an urgent need for a clear diagnosis. HyTEPS was called in to identify the invisible contamination in the network and provide a definitive solution beyond symptom relief.
Our engineers immediately carried out a comprehensive Power Quality measurement to identify the invisible cause of the faulty analogue-digital cards. This technical analysis showed that an excess of harmonics was polluting the installation, with the third harmonic in particular far exceeding the prevailing standards.
This harmonic distort ion caused a constant electrical load that disrupted sensitive process automation and caused components to fail prematurely. Without targeted intervention, the paper machine would continue to fail repeatedly, leading to unacceptable risks to continuity and high costs due to unplanned downtime.
To restore operational reliability, we implemented a HyTEPS active filter that corrects harmonic currents in real time. This proactive approach ensured that the installation immediately complied with internationally accepted standards, with our engineers fine-tuning the system to the specific load of the machine.
The result is a stable installation in which the third harmonic is reduced almost to zero and production outages due to these failures no longer occur. In addition to increased component life and reduced energy consumption, this filter has paid for itself in full for Sappi within a year. This result provides the desired security in every kilowatt.
Invisible Power Quality problems can disrupt your production process at any time. Don't wait until the damage is irreversible. Our engineers are ready to analyse your installation and restore peace of mind to your operations.
