How to measure the costs of poor power quality

摘要

THE INTERDEPENDENCE of various systems adds layers of complexity to this issue. Mission-critical systems exist throughout the facility and throughout the enterprise - power quality problems can bring any one of these to a grinding halt at any time. Installation - improper grounding, improper routing, or undersized distribution Operation - equipment operated outside of design parameters Mitigation - improper shielding or lack of power factor correction Maintenance - deteriorated cable insulation or grounding connections Even perfectly installed and maintained equipment in a perfectly designed facility can introduce power quality problems as it ages.
