From the electric circuit theory a model was established that enable the investigation of rural electric loads behavior for power rating up to 20 kW when the main power is a two phase system with tree wire 220/127V. This model will enable the signal harmonic content analysis at regions typically rural and its influence over voltage and current signals for typically rural loads, the voltage and current behavior for electrical appliances, lighting equipment and equipment feed by switching power supply and its influence over the system neutral current. The equivalent electrical circuit analysis was carried out using models developed for these types of loads and the waveforms for voltage and current with its harmonic contents was obtained by simulation.
