Current transformer error test
The current sensor error test generally uses the tested transformer to compare with the standard transformer, and the difference between the secondary currents of the two transformers is the tested transformer error.
This test method is called the comparison method. The standard transformer is required to be two grades higher than the tested transformer, and the error of the standard transformer can be ignored at this time.
If the standard transformer is only one level higher than the tested transformer, the error of the test result should be considered plus the standard transformer error.
