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.

Formerly Borri, Power Control (PCL) has received a glowing review for its electrical expertise and high performance UPS solutions from one of the world’s largest travel sites.

Due to continued business expansion, the global travel review company recently replaced its 60kVA, end of life unit with the purchase of two Borri B8000FXS 20kVA UPS units, which are now handling added capacity the company’s newest facility.

If you were to tell your boss a fifth of your output was being wasted and could not be accounted for, I doubt they would be too impressed. Where would you think the wasted output was coming from? Most managers would blame human error in their workforce, but they could be jumping to conclusions. Here, Keith Armstrong, global electromagnetic compatibility (EMC) expert at EMC Standards looks at a case where radio frequency interference (RFI) had a significant detrimental impact on a business

Managing director of Napit Certification, David Cowburn, discusses the release of the long awaited Bonfield Review and how its recommendations will improve energy efficiency in the UK and encourage the uptake of renewable technologies. Napit managing director of Standards David Cowburn explains

Chinese chequers

My thousands of devoted readers will recall the main reason why the new Prime Minister, Theresa May, placed a seven week moratorium upon endorsing any go-ahead for the Hinkley Point C new nuclear power station. It was the overt horror of those charged with overseeing the nation’s defences, at the prospect of a Chinese government-controlled company owning 40% of a British nuclear power station.

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.

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.

Abstract

An efficient and reliable data link is indispensable for the optimum implementation of the constantly growing need for building, extending and operating smart grids. The monitoring and control of remote components calls for comprehensive availability of measurement data and information to guarantee reliable overall operation.
