The electrical sector continuously deals with changes in its operating regulation and the market. Research is essential in this scenario to make energy use accessible to all and to contribute to lower tariffs. These aspects can cause profound technical economic impacts in all phases of the sector, notably: generation, commercialization, transmission, distribution, and consumption of electric power. These challenges require the development of innovative solutions for monitoring, planning, operation, maintenance, and commercial management of the electricity system in order to improve the entire chain, from generation to distribution.

It is in this context that Lactec contributes continuously to the optimization of internal and external processes of companies in the electrical sector through the development of new methods and equipment for application in the electrical sector within R&D projects. Some examples of this are:

  • Power system expansion and operation planning;
  • Energy planning of electrical systems;
  • Computer modeling applied to the electrical sector;
  • Study of the impacts of the connection of alternative energy sources on electrical systems;
  • Performance analysis of new technologies and electrical grounding systems;
  • Development of models and techniques for power quality management and electromagnetic compatibility studies;
  • Development, tests, and studies of protection elements of electrical systems;
  • Development of technologies for electric network maintenance;
  • Mapping and management of commercial and technical losses;
  • Development of models, methodologies and computational tools for electric market management;
  • Development of sensors for low, medium and high voltage;
