An energy analyser is used to measure, calculate and record voltages, currents, cos phi, power, consumption and harmonics. Based on these electricity measurements, it is possible to quantify an installation's energy demand and analyse the quality of the network.

Measurements of this type may be used in particular:

•  
  In the context of an energy audit, to estimate the breakdown of energy demand between the different stations of an installation;
•  
  In the context of a feasibility study for the installation of cogeneration, by establishing the real energy demand profile during a given period (generally one week).
