Which of the following voltage is a phase voltage in the delta connection?(a) VRN(b) VBR(c) VYN(d) VBNI have been asked this question in an internship interview.The above asked question is from Inter Connection of Three-Phase Sources and Loads topic in portion Polyphase Circuits of Network Theory

Answer»

Right choice is (B) VBR

To elaborate: A balanced three phase SOURCE is ONE in which the three INDIVIDUAL sources have equal magnitude with 120^ phase DIFFERENCES. VBR is a phase voltage in delta connection. And VRN, VYN and VBNare not phase voltages.
