Case Study: Because the Grid Isn’t Good Enough for Pharma

Case Study: Because the Grid Isn’t Good Enough for Pharma Pharmaceutical manufacturing is an intolerant business, particularly when it comes to electrical power. Even minor voltage fluctuations can disrupt critical processes, impact sensitive monitoring equipment and cause production to come to a stop. At a 600,000 square foot manufacturing and packaging plant in North Carolina,…

Case Study: The Semiconductor Industry Versus Voltage Sags

Case Study: The Semiconductor Industry Versus Voltage Sags A semiconductor manufacturer in California was experiencing consistent seasonal disturbances from lightning and other weather-related incidents between January and May each year, exposing production equipment to volatile sags and risking costly down time. Facility engineers needed a way to manage risk and deal with numerous unavoidable sags.…

UPS Protection Keeps the Trains a Rollin’

UPS power-backup systems installed to protect transportation control centers and other critical facilities are set to respond to even modest over-voltage conditions. In most industrialized regions, this is not a problem, as over-voltage conditions are rare. However, in very dense urban regions, such as New York City, over-voltage is an all-too-common condition in the summer months.

UV Disinfection Systems and Power Quality

There are 52,000 community drinking water systems in the United States that come under the scope of new rules issued by the U.S. Environmental Protection Agency (EPA) to improve public drinking water safety. Compliance with these news rules has significantly increased interest in the use of ultraviolet light (UV) water disinfection systems. However, UV systems are known to shutdown unexpectedly due to power quality problems: leaving the drinking water flow untreated. The purpose of this paper is to discuss the reason for the use of UV disinfection systems and the implications of and solutions for their sensitivity to power quality problems.

Energy Efficiency and Power Quality in Schools

Addressing energy efficiency in schools, the U.S. Department of Energy says, “For existing schools, implementing energy-efficient operations and maintenance strategies can enable school districts to save as much as 20% in energy costs, extend the life of equipment, and improve the overall physical environment in their school facilities.” DOE further comments about energy efficiency planning, “Addressing O&M considerations at the start of a project can contribute greatly to improved working environments, higher productivity, and reduced energy and resource costs.”
