POWER QUALITY DURING AN ELECTRICAL EXPANSION WITH A MANUFACTURER
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.

THE CHALLENGE
The size and complexity of the system required an in-depth interrogation of power quality and energy metering system, analysis of historical/future load, harmonic data, equipment types and network configurations. This was necessary to create a software model of the upgraded site and predict harmonic emissions at the point of common coupling. When sizing and developing specification for the passive filter design required, we had to account for changes in impedance (due to network switching), space constraints and environmental conditions.
HOW WE HELPED
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.
THE RESULT
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.
THE CLIENT
This world leading company manufactures semiconductors used in computers and other technologies throughout the world. The case study featured is based on work carried out in the company’s Irish facility, which produces the latest generation silicon microprocessors.
”"Our extensive power quality and harmonic analysis of the electrical distribution network allowed execution of a detailed and efficient design, which was successfully implemented by the customer."
