Maintaining Voltage-Current Phase Relationships in Power Quality
... Both these sources of errors are due to the magnetizing inductance required by the core and the impedance of the windings (see Figure 3). The resistive losses will cause ratio error and the inductance of the windings and core will cause both ratio and phase error from the primary to the secondary si ...
