CLIC Energia has published the fourteenth of total 30 projects selected for the R&D Magazine, 4th Issue, which was released on Aug. 17 during the 6th Congress of Technological Innovation in Electrical Power (CITENEL) and the 2nd Seminar of Energy Efficiency in the Electricity Sector (SEENEL), both held in Fortaleza (CE). The purpose is to present the results achieved with R&D projects to the society. The on-site publication follows the insertion order in the magazine.
The fourteenth article, elaborated by Ampla Energia e Serviços S/A and Instituto de Tecnologia para o Desenvolvimento (LACTED), addresses a system of reduced cost for remote cutoff and reactivation for Group A consumers (min. 2,3 kV). Through conventional methods, the power cutoff in this segment is a high-cost logistic procedure because it requires the shutdown of a part of the distribution line and the creation of alternative routes. The prototype, a box with battery and electronic circuits, has enabled to perform these operations in a connection to the concessionaire’s communication center or through a local command of the switch, by means of a data collector. The tests conducted in laboratories and a consumption unit covered by Ampla were successful. The power distribution company plans to improve the prototype for large-scale production.

Equipment enables remote cutoff and restoration of medium-voltage consumers Researchers of AMPLA and Instituto de Tecnologia para o Desenvolvimento (LACTEC) have developed a system that allows to perform remote power cutoff and restoration of Group A consumers (min. 2,3 kV). The current procedure employed in these activities is a high-cost logistic method, as the Group A consumer is supplied by low-voltage distribution systems. For this reason, cutoff requires prior shutdown of a part of the distribution line and the creation of alternative routes. With the new equipment, these actions can be performed through the concessionaire’s communication center or a local command of the switch, by means of a data collector. The prototype has a box with the components required for the cutoff and restoration operations. The box is protected to prevent water penetration, vandalism or interventions not authorized by the distribution company. The box also has, in separated compartments, a battery and previously assembled electronic circuits. The prototype has been tested in a laboratory and then installed in a medium-voltage consumer unit. The researchers have concluded that the project offers lower cost when compared to the system available in the market and it has all functions included. The next step is to present a new R&D project for the prototype integration and large-scale production. Technical Information |
