Photochemical Pollution Modelling In Complex Terrain
Ozone is considered one of the most significant pollutants with respect to the potential impacts to human health and natural ecosystem, both in terms of critical episodes and as long-term exposures. Consequently, in order to assess the comprehensive effects of photochemical pollution, not only ozone peak concentrations need to be examined, but also ozone exposures […]

Technical design requirements and test experiences on Composite Hollow Core Insulators regarding pollution performance under AC and DC stress
This paper is a common approach of manufacturers of insulators, electrical equipment, transmission system and test labs to verify the expected behaviour in laboratory and outdoor tests. For the electrical design of composite insulators, different material properties and shed profiles for AC and DC conditions have to be taken into account respectively, considering the recommendations […]

Safety aspects of MV and HV underground cables and accessories in urban areas
The booming of renewable power stations (solar and wind mill mainly), the increase use of Interconnectors and submarine cables, the construction of urban substations in big cities with intense population and the need to avoid the use the overhead lines (right of way and so on), are the main factors leading to the increasing amount […]

The Resiliency Continuum
Storm damage can wreak havoc on the electrical distribution system and instantaneously create a major impact on those who continuously depend on unfettered access to electrical energy. “Keeping the lights on” is a bedrock principle of utility operations, but is increasingly being challenged by more frequent and turbulent natural disasters. The quest for greater utility […]

Mistral Software for online Monitoring System
​The collection, storage and analysis of information concerning a dam are a critical part of surveillance activity toward managing the safety of the structure. An important part on handling of this information is the interpretation of data coming from the monitoring. In addition, the use of automatic instrumentation has resulted in large amounts of data […]

Optical PD detection in high voltage cable accessories
Optical partial discharge detection is a new method to perform diagnosis of the insulation system detecting optical signals which are coming up at the same time.This method does not work with the electrical signals which are caused in case of partial discharges though. On the basis of this different physical process, external electrical noise can […]
