1.	Calculate the displacement factor if the fundamental voltage is 24sin(140πt-240°) and fundamental current is 47sin(140πt-120°).(a) -0.5(b) -0.7(c) 0.9(d) 0.4This question was posed to me in unit test.Query is from Solid State Controlled Drives topic in section Introduction to Solid State Controlled Drives of Electric Drives
Answer» Correct option is (a) -0.5 The explanation is: The DISPLACEMENT factor is the COSINE of the ANGLE DIFFERENCE between the fundamental VOLTAGE and fundamental current. D.F=cos(120°)=-0.5.
