Eskom funding may be muffling dissenting voices on nuclear

  The lure of millions in Eskom funding appears to have muzzled two research institutions previously highly critical of the state-owned utility’s plans to procure a fleet of nuclear power stations. In the case of the Council for Scientific and Industrial Research (CSIR) amaBhungane understands that the CSIR’s Energy Centre has been effectively gagged since […]

Using bird-resistant insulators on high-voltage transmission lines

  Ararat Wind Farm, Australia’s third largest wind farm, uses enhanced silicone polymer (ESP) insulators on the 132 kV powerline to reduce weight, improve speed of installation and increase span lengths. These insulators are also bird resistant which is critical because the powerline is located in a high bird strike zone. The Ararat wind farm, […]

EIUG: No nuclear needed anytime soon

  The persistent speculation on a possible nuclear power investment in South Africa being progressed on an urgent basis is concerning, given the scale and inflexibility of such an irreversible commitment in a fast changing world.  Reassurances that we will only embark on such a programme at a scale and pace which the economy can […]

Estimating moisture in power transformers

  Modern technology and developments in signal acquisition and analysis techniques have provided new tools for transformer diagnostics. Of particular interest are dielectric response measurements where insulation properties of oil-paper systems can be investigated. Dielectric frequency response, (DFR, also known as Frequency Domain Spectroscopy, FDS), was introduced more than 15 years ago and has been […]

New twist in IPP battle as Eskom may close stations early

  Eskom has been vague when it comes to backing up its claims about five power stations which will have to close early due to the expected inclusion of more renewable energy producers. Not even the three unions that have met with executives from the power utility over the past few weeks have been given details about […]
