New nuclear build is justifiable, says WNA

  In a new report, Nuclear Power Economics and Project Structuring, the World Nuclear Association shows that new nuclear build can be justified in many countries on the strength of today’s economic criteria and identifies the key risks associated with a nuclear power project and how these may be managed to support a business case for nuclear investment. This is the executive summary of the […]

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 […]

Cabinet reshuffle: what this means for the energy industry

  South Africans are in a state of shock following President Zuma’s seemingly abrupt decision to reshuffle his cabinet.
