Analysis of harmonic pollution caused by typical loads in offices

An analysis of the harmonic pollution produced by different load scenarios in an office is presented in this paper. An experiment was carried out, in which typical load scenarios in office environments were reproduced. The devices used in the experiment were selected based on the characterization of the consumption groups in office environments in several countries. The analysis shows that THDi and TDD were different for each load scenarios, so the scenario of highest consumption was not the most polluted. Moreover, it was concluded that scenarios, which include plug-load devices, has the highest harmonic pollution.
