Phase Angle Error and Ratio Error for Potential Transformer (PT)

  • Phase angle error

In an ideal potential transformer, the primary and the secondary voltage is exactly proportional to the primary voltage and exactly in phase opposition. ... Phase Angle Error – The phase angle error is the error between the secondary terminal voltage which is exactly in phase opposition with the primary terminal voltage.
