Electricity is the type of energy most used today. Due to the effects of global warming and pollution due to the use of other types of energy, electrical energy is undergoing a very important development in all fields. In generation, primary energy sources are sought that do not pollute and are native, such as renewable energy. In the case of transport, it seeks to increase its efficiency and reliability. There are also developments in terms of consumption, looking for equipment (appliances, motors, machines, etc.) to be increasingly efficient. In addition, the sector of transportation of people and goods is increasingly related to the electricity sector. The development of electric mobility solutions (cars, train, etc.) is driving the development of energy storage systems and recharging systems. This is also related to the development of Smart Cities, where it is intended to achieve a more efficient use of electrical energy. In the end, all these developments will require technologies that allow monitoring of energy flows, storage systems and through advanced control systems to be able to make the most optimal regulation of the networks. All this is assuming that many of the alternative generation systems and loads are non-linear systems, due to the mandatory use of power electronics. As a result, there is greater harmonic contamination and occurrence of disturbances and events in electrical networks. Many of the elements connected in the networks become emitters and receivers of this contamination and events, which implies a reduction in the quality of the system and a possible source of breakdowns.

The purpose of the proposed GIR can be summarized in the following points:
• Develop electrical energy measurement systems adapted to these circumstances.
• Development of signal processing and analysis techniques with high harmonic content, in stationary and transient state.
• Development of event detection techniques, disturbances, loss of energy quality.
• Development of algorithms for the reliable calculation of energy and determination of its quality in contaminated environments.
• Study of the effects of the loss of energy quality on the facilities themselves, particularly in hospitals and in the United States. and on the loads connected to them, in particular electric motors.
• Energy efficiency studies in facilities, particularly hospital ones.
• Development of detection techniques and fault diagnosis in induction motors, particularly in non-stationary operating situations.
• Integration of renewable energy sources in distributed generation, in Smart Grids and isolated systems.

In summary, the fundamental purpose of the research group is basic and applied research in electrical systems, installations and equipment, especially in aspects related to its maintenance and the analysis of its reliability and quality of service. These lines of action apply to any installation and equipment within the electric field but it is necessary to highlight that the work team has extensive experience in its application in the railway and hospital field.

The main objective of this GIR is the dissemination of the knowledge acquired through the following actions:
• Scientific publications in indexed journals.
• Participation in congresses.
• Direction of doctoral thesis.
• Collaborations with other groups of the UVA and other universities, national and foreign.
• Technology transfer to the public and private sector:
• Advice to companies and public sector organizations.
• Collaboration agreements or agreements with companies and public sector organizations in R & D & I projects.
• Contracts with companies and public sector organizations.

• Detection and diagnosis of failures in electric machines in stationary and transient state
• Measurement, calculation and analysis of the quality of electrical energy
• Development of instruments for measuring electrical energy
• Studies on electrical energy efficiency
• Maintenance in electrical installations
• Reliability in electrical networks
• Renewables integration with distributed generation in Smart Grids and isolated systems
