A new method used in error and VI characteristics measurement of current transformer is developed based on the equivalent model of current transformer. Using this method, the up-flow unit and the standard current transformer are not necessary. And more characteristics of current transformer can be inferred. The current transformer calibrator developed based on this method can carry out rapid and precise...
A new type of current transformer (CT) calibration approach is introduced, which is based on the current transformer equivalent model. We can analysis the CT's performance by calculating its internal parameters. The current transformer error, voltage characteristics, 10% error curve can be measured, solving the problem of up-flow unit and the standard current transformer is no longer needed in the...
