"Maintaining power in remote locations" -Plant Engineering
This article provides valuable information about why a UPS not rated for high temperature and rugged environments can be problematic. Aspects of UPS design, including batteries, are reviewed and how environmental conditions that can render a standard UPS to be unsafe and unreliable. It is critical to use a UPS with both the appropriate design and safety agency listing to operate in the installed environment.
"Secure supply for the SCADA system" -Water/Waste processing
In wastewater facilities, industrial-grade UPS reduce maintenance whereas office-grade can fail several times annually. This article reviews how a wastewater’s automated systems, such as SCADA and RTUs, function in harsh environments and are adversely affected by power problems. Unscheduled downtime occurs due to the improper use of office-grade UPS in these harsh environments. Water utilities can optimize operations by using a rugged online industrial UPS with a wide temperature range, often from -22° F to 149° F, and batteries with a 4 year service life at 122° F.
"Uninterruptible power supply usage in harsh environments" -ECN
An uninterruptible power supply is now used in many critical applications, including those located in harsh environments. This article reviews the industrial setting and how manufacturers have designed industrial UPS with such features as: high operating temperature, conformal coating and NEMA rated enclosures. It also provides important information about the UL 508 standard for equipment installed in industrial control panels.
"Power Conditioning, backup of SCADA systems in harsh environments" -Pipeline & Gas Journal
There are critical issues to consider to protect gas and pipeline SCADA systems from power problems. This article explains what to look for in an industrial UPS: key design features, operating temperature range, UL listing and wide temperature batteries. It also points out important areas to protect in gas and pipeline systems.
"Effects of extreme temperatures" -EC & M Magazine
Installing a UPS in extreme temperature applications presents many critical considerations, namely maintaining reliable operations. This article presents important UPS features.-including detailed charts and data about the effects of higher temperatures on battery life. An oil/gas application is presented as an example.
"Is your UPS rated for industrial environments?" -Electronic Products
A step-by-step guide on what to look for when selecting an on-line uninterruptible power supply (UPS) for use in industrial environments. The UPS must operate flawlessly in a harsh environment for 10-15 years and require minimal maintenance. Most importantly and yet most overlooked is the effect of high temperature - the article discusses how to choose a reliable hi-temp UPS. Other key issues include UPS battery selection, dealing with airborne contaminants, etc.
"Reliable power could have prevented Fukushima disaster" -ECN
The realities of what could have prevented the Fukushima disaster are explained here—specifically that the plant did not have a reliable source of power. The backup power generators were rendered useless because they were installed at or below ground level and flooded by the tsunami. This article covers how to prevent such costly disasters by doing thorough site planning and implementing the appropriate power protection.
"Empowered with uninterruptibility" -Chem.Info
What does a major water utility do to ensure a clean water supply? El Paso Water Utility found that clean, stable power was critical for lab equipment to operate correctly. This case study traces how EPWU experimented with lower cost “Smart UPS” for power protection and saved money initially. It describes how they then faced unexplained aborted tests with “no fault” errors and lost time, money and peace of mind. In the end, a high quality on-line UPS resolved the problems and saved EPWU countless hours and dollars.
