Review of recent research towards power cable life cycle management

Power cables are integral to modern urban power transmission and distribution systems. For power cable asset managers worldwide, a major challenge is how to manage effectively the expensive and vast network of cables, many of which are approaching, or have past, their design life. This study provides an in-depth review of recent research and development in cable failure analysis, condition monitoring and diagnosis, life assessment methods, fault location, and optimisation of maintenance and replacement strategies. These topics are essential to cable life cycle management (LCM), which aims to maximise the operational value of cable assets and is now being implemented in many power utility companies. The review expands on material presented at the 2015 JiCable conference and incorporates other recent publications. The review concludes that the full potential of cable condition monitoring, condition and life assessment has not fully realised. It is proposed that a combination of physics-based life modelling and statistical approaches, giving consideration to practical condition monitoring results and insulation response to in-service stress factors and short term stresses, such as water ingress, mechanical damage and imperfections left from manufacturing and installation processes, will be key to success in improved LCM of the vast amount of cable assets around the world

Myths and Realities of Governance and Corruption

A number of popular notions and outright myths on governance and corruption are addressed in this chapter. We distinguish clearly between governance and anti-corruption, while probing the links between both notions. In so doing we challenge the conventional definition of corruption as being too narrow, legalistic and unduly focused on the public sector, while underplaying the role of the private sector. We then challenge the notion that governance and corruption cannot be measured, showcasing the latest worldwide governance indicators, measuring six dimensions of governance and cover over 200 countries, based on multiple sources, including the EOS. Thanks to these governance indicators and related datasets, it has been possible to study the extent to which governance and anticorruption matters. Consistent with the adage that 'sunlight is the best disinfectant', the potential gains of embarking on a transparency reform strategy is given particular prominence in this chapter, and a detailed 12-point 'scorecard' for countries to rate themselves in terms of the implementation of concrete transparency measures is presented. The chapter then concludes with a call for a global compact on governance and anti-corruption, where the G-8 and other rich countries, the multinationals, IFIs, civil society and the government leadership in the emerging economies share responsibility in making concerted progress.corruption; transparency; governance
