The length of XLPE-insulated underground cable lines in the European HV / EHV network is experiencing a fast growth due to the increasing number of submarine interconnections and suitability to be installed also in urban area with nil visual impact after installation. Use of cable stretches in combination with overhead lines has proven to be […]
A 3D computer model has been developed for predicting magnetic fields in order to comply with legislation concerning safety and environment issues. The developed software , named “EMF-CS”, allows the user to predict and simulate magnetic fields generated by electrical MV/LV substations whose magnetic field emission has to be evaluated inside the plant as well […]
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 […]
I sistemi di monitoraggio permettono agli ingegneri il controllo di strutture o del territorio avendo a disposizione informazioni in merito al comportamento di strutture o di dissesti al fine di identificare i rischi potenziali. I sistemi di monitoraggio sono dotati di opportuni software di gestione che vengono in aiuto per l’analisi dei dati e a […]
The Electric power System has a very important role for the economic development and welfare and is at the heart of a sustainable way to use energy. It is the largest machine ever been engineered: in Italy 60 thousand kilometers of transmission power lines – one and half time the circumference of the Earth – […]
The increasing global demand for electricity in both industrialized and emerging markets is driving demand for cables systems. We carry out type tests to verify the design of LV, MV and HV cables and their accessories. Type testing allows you to prove that your cables and cable accessories meet the highest quality standards to deliver […]
Optical PD detection in high voltage cable accessories A novel method in order to perform diagnosis of the insulation system is optical partial discharge detection. This method does not work with the electrical signals which are caused in case of partial discharges but rather detects the optical signals which are coming up at the same […]
Energy utilities need on-site AC high-voltage acceptance tests on their cable systems and switchgear, in order to ensure the quality of their transmission systems; such tests need to be performed on site with special equipment as well as remarkable measurement technology and diagnosis at voltages of up to 500 kV. Complete acceptance tests such as […]
The 2nd Advanced cable Middle East 2016 conference held in Dubai from February 2nd to February 3rd brought together about 100 senior representatives from leading companies and organizations internationally and regionally. Delegates took part in detailed debates investigating the challenges and opportunities that lie ahead for the Middle East market. The conference proved to be […]
1st Advanced cable Middle East 2015 conference brought together over 110 senior representatives from leading companies and organizations Internationally and regionally. Delegates took part in detailed debates investigating the challenges and opportunities that lie ahead for the Middle East market. The conference proved to be an excellent forum for discussion and knowledge sharing as well […]
Medgrid is a European industrial initiative to study the feasibility of a 1,000 MW HVDC transmission project connecting North Africa to Europe. Medgrid assigned to a Consortium led by CESI (together with Intertek and Parson Brinckerhoff) a feasibility study aimed at providing answers to technology and cable limits, laying methods, maintenance, costs and planning, for […]
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 […]
Worldwide demand for new T&D networks will increase in the near future pushing the utilities to install a larger number of high voltage equipment like cable terminations, bushings and surge arresters. Meanwhile the attention to environmental and safety issues is generally increasing . The aim of this paper is to analyze the potential risks associated […]
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 […]
In a changing electrical market, driven by renewable energies, the target is to get wind or solar energy to the consumption centers . Nowadays Transmission System Operators (TSO) are worldwide searching for innovative solutions in developing the transmission grid and, as a result, it is likely that the application of extra high voltage AC and […]
The reversal of voltage polarity is essential in HVDC cablesystems with Current Source Converters (CSC), since it enables to revert the direction of the power flow. Mass Impregnated Non-Draining (MIND) cables are known tobe able to withstand the voltage polarity reversal without particular problems. TERNA, the Italian Transmission System Operator (TSO), has introduced since many […]
High-voltage direct-current (HVDC) technology is a growing field in the T&D sector, allowing transmission of bulk quantities of energy with a reduced impact on Infrastructures and reduced losses. The performance level of today’s HVDC solutions allows to gain advantage from technical, economic and environmental points of view. HVDC power transmission becomes more and more […]
