Symmetrische Sternschaltung berechnen, Beispiel (Drehstrom 02)

0:00 Problem with Solution 0:39 Solution a) Nominal voltage 2:08 Solution b) Nominal current 4:07 Solution c) Resistance 4:48 Solution d) Power 5:30 Solution e) Power 2 8:05 Quiz For this problem with solution, I will first calculate the simplest version of a star connection: Symmetrical, meaning all three phases are the same and only have active resistors. The resistors are three heating elements. The heating elements do not develop a phase shift. Their reactive power is zero, and thus the apparent power is equal to the active power. What are the voltage, current, resistance, and power values? What power does the star connection produce if one phase fails? At the end, you can test your knowledge with a quiz: What is meant by "phase"? Why don't heating elements produce a phase shift? What is power factor?
