Power Quality During an Electrical Expansion
This large semiconductor manufacturer was undergoing an expansion and needed to detail its power quality and energy metering system. Our work resulted in high cost savings for the facility, due to an increased system performance and prevented penalties from the utility provider.
Premium Power Role:
We predicted levels of harmonic currents at the main MV distribution and specified a passive harmonic filter suitable for the level of predicted distortion, to mitigate against any adverse effects on the plant equipment, as well as to comply with future planning requirements for harmonic emissions set out by the utility provider. This resulted in high cost savings coming from increased system performance and prevented penalties from utility providers, relating to low power factor and high harmonic contribution.
After conducting an arc flash study for this client we identified a number of problems with the protection coordination. It was decided that the best option would be to carry out a protection coordination study to fully grasp the extent of the issues.
Premium Power supplied a filter design which was subsequently installed. Total harmonic voltage distortion across the MV part of the network was maintained at 3%, allowing compliance with IEC 61000-6-3 limits and preventing future failures of critical devices, reducing the energy losses due to excessive currents and extending lifespan of mission critical power equipment.
