آشنایی با جریان سه فاز
The three-phase current in a circuit whose inductive wiring (armature) is prepared from three separate coil groups, each of which has a phase difference of 120 electrical degrees.
انواع اتصال در سیستم سه فاز
در سیستم سه فاز معمولاً از سه نوع اتصال استفاده می شود :
الف- اتصال ستاره
ب- اتصال مثلث
ج- اتصال مختلط
-محاسبه جریان و ولتاژ در اتصال ستاره
As we know, in the star connection, the difference between the level of each phase and the neutral wire forms the phase voltage (UP) and the difference between the level of each phase and the other phase forms the voltage (Ul). The value of line voltage is obtained from the sum of two phase voltages. Therefore, to obtain the value of Ul, we must draw the result of two phase voltages and calculate its value. In this way, we draw one of the vectors along its own length and then draw the vector with its side vector.
