What is the correct relationship between the phase voltage and line voltage in Delta connection with the positive sequence?(a) VL=Vp(b) VL=√3Vp(c) VL=√2Vp(d) IL=√2IpThe question was posed to me in unit test.My question comes from Power Rating Determination of Electric Motors for Different Applications topic in section Rating and Heating of Motors of Electric Drives

Answer»

The CORRECT option is (a) VL=Vp

Explanation: In the delta connection line VOLTAGE is the same as the phase voltage. The line current is √3 TIMES of the phase current and leads by 30°.
