The 7th Cigré southern African regional conference was held at the Lord Charles hotel in Somerset West from 7 – 11 October 2013. The program consisted of a day of tutorials, a study group colloquium, two days of technical papers and a day of technical visits. An interview of Klaus Frölich, president of Cigré, is included… (more)

The Cigré B5.31 brochure describes a generic setting management process, based on the “best practises” of utilities based around the world. The process requires that all the changes that could affect the settings of a protection relay during its life time are identified, controlled and validated. This is necessary to ensure power system security is maintained, even during constrained operating scenarios… (more)

Age, obsolescence, and network evolution or community requirements are common issues impacting electrical substations throughout the world and all these lead in the short or long term to the inevitable necessity for renewal of existing substations… (more)

In recent years, the integration of renewable energy sources (RES) on electricity power systems across the world has increased considerably. According to most estimates, this development is set to increase even further over the coming decades, and the majority of this increase is expected to be from variable non-synchronous renewable (VNSR) generation. This fluctuating energy will alter the fundamental behaviour of power systems and introduce new challenges… (more)

This feasibility study is an initial investigation into whether large HVDC grids are economically interesting and technically possible to build. The reason for the interest in HVDC grids is that in many parts of the world there is a growing need for more transmission capacity due to increasing production of renewable energy at remote locations and an increasing trade of electricity… (more)

The past few years have seen a considerable increase in the integration of renewable energy sources (RES) on electricity power systems worldwide. RES integration is set to grow in the coming decades, and experts expect most of the increase to be from variable non-synchronous renewable (VNSR) generation… (more)

The history of Cigré in South Africa? How long has Cigré has been going in South Africa? Cigré has been going in South Africa for about 70-80 years. There are certain rules that you have to abide by to set up a national committee such as having a certain number of local members, putting together a constitution and submitting  that to Cigré in Paris. If you look at New Zealand as the latest national committee, they used to be part of the Australian national committee, and Cigré have just allowed them to join as an independent national committee… (more)

The national committees of Cigré elect a chairman who is entitled to sit on the administrative council of Cigré. This body is the governing body of Cigré and consists of all countries in Cigré with national committees. The steering committee (previously the Cigré executive) is the body that advises the administrative council on certain issues as well as takes decisions of an urgent nature… (more)

Europe-wide design projects for new generating plants, in particular new nuclear generating stations, as well as the power failures in Germany in March 2006 caused by extreme weather conditions and in November 2006 caused by electrical overloads on power lines are making the construction of new transmission lines urgently necessary, and thereby attention is being drawn to the current state of electrical transmission line technology in the world… (more)

The first graduation of short course Radmaste mathematics and science matric teachers took place at the end of last year. The program comprises full year part-time study which ends in an examination and the award of a certificate of competency by the University of the Witwatersrand, a fully recognised formal qualification… (more)

The Cigré Steering Committee, consisting of leading industrialists from USA, Canada, Brazil, Argentina, Australia, Japan, China, Russia, South Africa, Germany, France, Spain, and the UK, will meet in South Africa from 24 – 27 April 2012. During the meeting a South Africa day will be held with presentations from Eskom (on the electrical energy situation), ABB (on production of large transformers) and Pfisterer (on production of HV insulators). This is an opportunity to showcase our abilities to other countries. The day will include a technical visit to an electrification project… (more)

This is a summary of the discussion which took place during the 2010 open session of the Cigré Study Group A2: power transformers. The scope of SC A2 covers all kinds of power transformers, including industrial, DC converter transformers and reactors and transformer components, and activities are related to design and manufacture, application of materials, utilisation, safety and environmental aspects, economic/commercial aspects and quality assurance and testing… (more)

This is a summary of the discussion which took place during the 2010 open session of the Cigré Group B2, Overhead Lines. The session dealt with three specific preferential subjects. Twenty seven papers were published with almost 60 prepared discussions showing a high interest in the preferential subjects… (more)

It is with great pride that the SA National Committee of Cigré would like to announce that Rob Stephen has been elected to the international Steering Committee of Cigré during the current Paris session. This significantly increases our profile as a country within Cigré, and allows us great opportunity to influence the technical direction that the organisation takes. Please join the commitee in congratulating Rob on this achievement – which is based on his personal contribution over many years to the work of Cigré, as well as the excellent level of contribution made by South African members of Study Committees and Working Groups… (more)

Cigré stands for “International council on large electric systems”. It is a body of experts whose primary focus is the dissemination of information for the good of the electrical power transmission industry. The issues facing Cigré are, due to the nature of its activities, issues facing the power transmission and distribution industry as a whole. This editorial hopes to summarise some of these issues… (more)

Clive Errol Burchell was born on 3 Aug 1933, and grew up and went to school in Boksburg. There is still a photo up in Boksburg High School of him as a team captain. He qualified as an electrician and then studied further to become an electrical engineer.
