Harmonics: Today’s problems and its solution

Voltage harmonics are due to the voltage drop produced by current harmonics on distribution line impedances. This is illustrated in Fig. 2. So, reaching these limits depends on two factors: Emission level of the receivers: The more emissions, the more distortion caused by the voltage drop produced by harmonic currents in the network
