【正文】 technologies, that is , there exists a huge potential to renew the existing street lighting and save in the energy consumption[1]. It is estimated that nearly the 5% of the energy used in lighting applications is consumed by the street lighting, being the most important energy regarding the energy usage in a city . New industrial approaches have been develop recently in order to achieve an efficient lighting, which can be summarized in improvements in lamps39。 technology and electronic ballasts, soft start systems, noiseless performance and lighting automatisms. Saving energy in street lighting can be achieved with two methods,by controlling the light duration or by dimming. There also exist remote management systems that allow the user to keep an individual remote control and monitorization of every single lamp. By making use of these systems the operator can monitor the main parameters of any light point from a central or mobile unit. The obtained data are ready for processing, allowing the reckoning of statistical consumption, lamp status, voltages, anomalies,ect,decreasing the mean time to repair. Another interesting parameter could be the arc voltage level, which can mean the change of a corrective or preventive maintenance to a predictive one, saving money in the maintenance cost. In order to have an optimum control, the remote management system should allow a duplex or half/duplex mun
