2. The highest measurement accuracy of the CT analyzer: 0.05% / 2 minutes during field calibration;
3. Easy to use. The CT Analyzer can test all types of single-rate and multi-ratio current transformers and evaluate current transformers in seconds with the push of a button.
4. CT analyzers can be automatically evaluated according to IEC and IEEE standards;
5. CT analyzer debugging time is short (automatic test time <2 minutes);
6. Excellent workplace safety - test runs up to 180V;
7. CT tester is small in size and light in weight (<9kg / 19.8lbs), which is convenient for on-site testing;
8. CT analyzer adopts professional pull box design, which is easy to carry and anti-vibration.
