2 Current-Transformer Phase-Shift Compensation and Calibration An analog RC filter is the traditional way to overcome the phase shift problem; however, RC filters are not very satisfactory because of their cost, stability issues, and the need for time consuming manual calibration. These drawbacks are overcome with digital compensation and automated calibration. This

The tolerance of the CT phase shift must be known to determine the maximum and minimum phase shift. The phase shift step is chosen so that the error due to inexact compensation remains acceptable. For example, if the step size is 0.1 and the minimum power factor is cos(60 ) = 0.5, the maximum error is 1 - [cos(60 + 0.1 ) / cos(60 )] = 0.3%.
