Description

Task 031524-0100-0001 (judgment of ElektroHelp). Three-phase circuit in star connection.

For the three-phase circuit of the line voltage Ul and complex impedance phases, as follows:
1) represent schematic diagram (star with neutral conductor);
2) to determine the phase and line currents;
3) to determine the current in the neutral conductor;
4) determining the active and reactive power of the entire circuit and each phase separately.
Built in scale vector diagrams of currents and voltages in the complex plane.
Given: Ul = 220; ZA = 5 - j5 Ohm; ZB = j8 Ohm; ZC = 4 + j3 ohms.

Additional information

The calculation of the four-star. Determination of currents and powers symbolic method.
