So, the scene has been set, we have our smart tool, the phone or tablet; we have Apps and we have wireless, 4G and other smart networks which is great news, but what does it really give us? Well to be honest, this is where the hype kicks in and perhaps the confusion. For a definition of the Internet of Things I refer you to this definition from Wikipedia; the Internet of Things is the internetworking of physical devices, vehicles (also referred to as ‘connected devices’ and ‘smart devices’), buildings and other items embedded with electronics, software sensors, actuators and network connectivity that enable these objects to collect and exchange data

Netwise Hosting is an innovative and forward thinking company, and one of London's leading data centres. Based in central London, their facilities and systems have been designed and built in-house, allowing for strong working relationships with all the technology suppliers, not least EcoCooling. Netwise have just completed their second EcoCooling installation within their estate, This case study documents these first 2 phases and possible future plans.

As network operators and consumers become more and more aware of the importance of the security of supply in electrical power systems, they are becoming increasingly interested in the continuous measurement of power quality. In order to identify problems at an early stage and to be able to take appropriate preventative measures, the first step is to use a suitable measuring system to closely analyse the supply system or technical equipment over a longer time period. Depending on the specific facility and application, the requirements to be met by a suitable measuring system are very varied and include a wide range of different measurement functions.

Patrick Donovan is a senior research analyst for the Data Center Science Center at Schneider Electric. He has over 20 years of experience developing and supporting critical power and cooling systems for Schneider Electric’s IT Business unit including several award-winning power protection, efficiency and availability solutions. An author of numerous white papers, industry articles, and technology assessments, Donovan's research on data centre physical infrastructure technologies and markets offers guidance and advice on best practices for planning, designing, and operation of data centre facilities

Early this morning as I sat here in New England with shovelled snow almost to the window sills, I came across an interesting article. It talked about the Danish practice of hygge (pronounced ‘HUE-gah’; which is their time-honored means of coping with long, cold, and dark winters.  In Denmark their hours are marked by dreary and cloudy conditions 64% of the time and is never hot.  As psychologists know well, long periods of cold and dark can lead to feelings of isolation and depression.  Yet despite the odds being stacked against them by Mother Nature, the Danes somehow manage to rate themselves as being the happiest country in the world.  How is this so?  

There’s no doubt that Cloud, the Internet of Things (IoT) and digital services are some of the hotter topics today. Add in big data and analytics, machine to machine (M2M) data and artificial intelligence and you’ve pretty much got all of the major technology trends facing us today. So it came as no real surprise that most of these terms were all liberally sprinkled into questions I was asked to field during the recent introduction of StruxureOn in the UK and Ireland. Henrik Leerberg, director of marketing and strategy for data centre managed service & software at Schneider Electric explains

Consistency is the hobgoblin of little minds

By the time you read this, it seems highly likely that Prime Minister Theresa May will be celebrating nine months in office, by intervening overtly in the prices that energy firms can charge their householders. And receiving congratulations from the tabloid newspapers for doing so.

The objective of this booklet is to provide today's engineer with useful technical information and as an aide-memoir when you need to refresh your memory. Conversions and formulas that are important and useful to the engineer, scientist and technician, independent of discipline, are covered in this useful booklet.

The guide covers:

  • Abbreviations for Physical Quantities
  • Units of Physical Quantities
  • System of Units
  • General Mathematical Formulae
  • Engineering Concepts and Formulae
  • Applied Mechanics
  • Fluid Mechanics
  • Thermodynamics

This handy booklet will be a valuable addition to anyone involved in the Electrical discipline. It covers key concepts, graphs and formulas related to Power Quality, Power Systems Protection and Substation Automation.

Some trends in IT viewed over the long term may seem to be cyclical. One in particular has seen IT deployment move from centralised processing to personal computing and back again. Matthew Baynes, datacentre strategy and business development director, UKI, Schneider Electric explains

Tim Brown from cable management specialist, Unitrunk, discusses the increasing importance of BIM and outlines the challenges and opportunities it brings for the cable management sector

Fascinating first report

This month we are due to see the first report from Lord Chris Smith, the Environment Agency’s former chairman, into the risks and benefits of shale gas.

The choice of cooling architecture, including hot and cold air containment, is of paramount importance for minimising the OPEX of a data centre. However, an effective control system is also essential when hoping to achieve the maximum energy efficiency and PUE. White Paper 225 details the different levels of cooling control as a basis for achieving the optimal balance of performance and efficiency.

In 1965, Gordon Moore, co-founder of Intel, predicted that the complexity of integrated circuits with minimum component costs would double every 12 to 24 months. Although „Moore‘s Law“, as it became known, has been challenged and rephrased repeatedly since then, it remains an accurate reflection of the general principle which lies behind our modern-day acceptance of technological progress: the continuous improvement of performance while minimising size and cost at the same time. This type of progress does not only bring positive effects for ordinary consumers in their day-today lives, it also brings benefits in the field of power generation and distribution with the use and continued development of IEDs in many different areas. The latest generation of IEDs must meet a multitude of different requirements, including high reliability and system stability. But the costs which automatically arise in connection with the installation, configuration and operation of a new IED should also be kept as low as possible. A number of different ways to optimise costs of this kind are described below, using the latest generation of SHERLOG CRX fault recorders from KoCoS Messtechnik AG by way of example:

Digital remote monitoring services deliver real-time monitoring and data analytics support via the cloud to data centre operators. The obvious benefits of maximum uptime with minimal overhead and improved efficiency are nevertheless offset by the threat of such systems being used as an avenue for a cyber attack. With proper precautions taken at both the design and operations stages, these threats can be minimised.
