WebThe two parameters which can be calculated from the open circuit test of transformer are R o and X o. They are calculated as follows. Step 1: Calculate no load power factor (cos φ o) The wattmeter reads the real power input. Therefore, W o = V oIo cos φ o. or cosφ o = W o /V oIo. We can calculate φ o from this. Step 2: Calculate Im and Iw :
