The sector maintains national standards for single- and three-phase power via waveform sampling. It develops advanced measurement systems for Power Quality in smart grids and characterizes energy storage devices using tomography and impedance spectroscopy.

The sector establishes and maintains the national standard for single-phase and three-phase power and energy through the simultaneous sampling of voltage and current waveforms under sinusoidal conditions.

Alongside conventional measurement systems and methods, the development of innovative methods and measurement systems continues, based on precision samplers and wideband voltage and current transducers, to ensure traceability of measurements of parameters associated with Power Quality within smart grids.

More recent developments of the activity include the characterization of electrochemical devices for electrical energy storage and conversion (batteries, supercapacitors, fuel cells) using electrical resistance tomography techniques (conductivity mapping of electrodes, current collectors, membranes) and electrical impedance spectroscopy for the identification of relevant electrical parameters (e.g., state of charge, state of health, capacity, etc.).
