CORRENTE TRIFÁSICA ( Professor Paulo Fernando Ribeiro ) - INGLÊS

AC is generated on a large scale at low cost. The generators used are three-phase, have three groups of coils.

The energy is generated through electromagnetic induction to each coil group called phase

Due to their physical layout each coil group generates electrical energy at different times

It is worth remembering: between phase and neutral simple voltage; and phase and phase composite voltage. Composite voltage is 3 times higher than the single voltage

Star Circuit

The current passing through the line is the same as that which passes through the elements, ie the line current equals the phase current

The common point between the three elements is called neutral.

When the charges are connected between phase and neutral (R1 = R2 = R3)

With three equal loads on a star circuit, no current flows in the neutral conductor.

Circuit triangle (Delta)

The loads are connected between phases in a three-phase circuit
