(1) CT variable ratio range:
The 5A / 5A~25000A / 5A (5A / 1A / 1A~5000A / 1 A) turn ratio error of ± 0.2%
Error measurement range:
5A/5A～5000A/5A（5A/1A～5000A/1A）
Accuracy range of the inspected current transformer: 1.0, 0.5, 0.5S, 0.2, and 0.2S
For 1% (grade S) or 5% test points, the test error mainly lies in the deviation of the instrument automatic picking point, that is, the deviation of the percentage table reading and the heart piercing location of 1 turn (which also exists in the traditional verification methods).Therefore, the error difference between the two verification methods may be large or small.
Machine accuracy: 1 / 3 of the measured current transformer error limit (see Appendix I) (Note: the standard transformer and calibration errors are 1 / 5 and 1 / 10 of the transformer error limit and Z are 1 / 10, the electromagnetic field is 1 / 10 of the transformer error limit, and the other errors are 1 / 10 of the transformer error limit. The comprehensive error is added to the above, as 1 / 3.33 <1 / 3 of the error limit of the inspected transformer. )
accuracy: ±0.05%
