1. Hi Whitepaper Technical guide: techniques for monitoring and protection of power plant equipment, Click following link here to download.
Hi Description: This guide from Sensonics explains the basics of vibration and expansion measurement techniques relating to turbine and auxiliary plant equipment. The guide starts with an introduction to the basic transducers available for plant mounting with ASSOCIATED options and details the various measurement techniques used as standard throughout the power industry. This is followed by typical equipment protection configurations for safe plant shut down. In the final part of this guide, the system components are introduced and special measurement regimes are discussed.
2. Hi Whitepaper Application note: developments in battery stack voltage measurement, Click following link here to download.
Hi Description: AUTO MOBILES, aircraft, marine vehicles, uninterrupted power supplies and telecommunications hardware represent areas utilising series-connected battery stacks. These stacks of individual cells may contain many units, reaching potentials of hundreds of volts. In such systems, it is often desirable to accurately determine each individual cell’s voltage. As Linear Technology explains, obtaining this information in the presence of the high ‘common-mode’ voltage generated by the battery stack is more difficult than might be supposed.
3. Hi White paper: IEC 62310 for static transfer systems — ensuring performance and safety, Click following link here to download.
Hi Description: Before the IEC 62310, prior to 2008, there was no product standard for the ‘static transfer system’ (STS). The closest standard used by manufacturers was the IEC 62040 (uninterrupted POWER SYSTEMS, or UPSs). Indeed it is a good reference, but the weak points are definitions and tests. In fact, in UPS standard IEC 62040 there is no definition for the STS or of the following: preferred and alternate source; normal mode of operation; transfer and re transfer; switching mode; synchronous and asynchronous transfer; sensitivity; and protection class. This paper from Socomec explains why users should ask for IEC 62310-compliant STSs.
4. Hi White paper: long-stroke/high-resolution tip-tilt mechanism, Click following link here to download.
Hi Description: Multi-degree-of-freedom (DoF) mechanisms are widely required in micro or macro manipulation fields as well as in optronics functions. Commonly available mechanisms may be divided into two main categories. The first is industrial robots (serial or parallel). These offer a large range of motion in rotation and translation. Their resolution is usually limited in the sub-millimetre range. The second category achieves very high-resolution motion (sub-nanometre) but is limited to a few decades of microns. A way to combine both long stroke and resolution is to use piezo MOTORS into multi-DoF mechanisms. The aim of this paper is to present a combination of both advantages into a low-volume tripod actuator. The tripod actuator from Cedrat Technologies is a three-DoF mechanism offering +/35° rotation around the X and Y axis and a 10mm Z translation stroke into a low volume of Ø50x50mm.

5. Hi Whitepaper: Technical article: water efficiency can be a steamy issue for power plants, Click following link here to download.
Hi Description: Generating power can mean the use of a diverse range of technology, from a simple coal-fired facility to the latest in nuclear plants. But all have one thing in common: the need to control heat and produce steam — and this generally necessitates using large volumes of process water. This article from Industrial Purification Systems discusses the use of modern filtration technology as a means to improving both HEAT TRANSFER efficiencies and plant protection.
6. Hi White paper: Seaward Group considers the preventative role of portable appliance testing, Click following link here to download.
Hi Description: In this white paper, Jim Wallace, associate director of the Seaward Group, offers an overview of the in-service inspection and testing of electrical equipment and appliances. It is doubtful whether any single issue has raised as much discussion and debate in the ELECTRICAL SERVICES industry as that provoked by portable appliance testing.
7. Hi White paper: how industry leaders use people, processes and technology to drive innovation, Click following link here to download.
Hi Description: Companies want to raise the bar on innovation from incremental improvement to the kind of innovation that shows up in the annual report. Breakthrough innovation is visible to customers, the MARKET, and investors. As Lana Kington, director of global R&D innovation management for Mead Johnson Nutrition, points out: ’Whenever our management speaks to investors, they consistently highlight our innovation performance because of its importance to our consumers, our business and our reputation.’ Others agree, including Sindy Wilson, director of product portfolio analytics and insights for Manheim Auction: ’We are the industry leader and we drive innovation, it’s very visible and a very high priority.’
