Question

ummm what do u mean by star delta conversion

Answer 1

Answer:

The replacement of delta or mesh by equivalent star connection is known as delta star transformation. The two connections are equivalent or identical to each other if the impedance is measured between any pair of lines. That means, the value of impedance will be the same if it is measured between any pair of lines irrespective of whether the delta is connected between the lines or its equivalent star is connected between that lines.
