Features and Advantages
Product Features
1. Easy to use. The CT Analyzer allows all types of single and multi-ratio current transformers to be tested, and it evaluates the current transformer within seconds with the push of a button;
2. Highest measurement accuracy: 0.05% / 2 min when calibrating on site;
3. Automatic evaluation according to IEC and IEEE standards;
4. CT analyzer debugging time is short (automatic test duration <2 minutes);
5. Excellent workplace safety – Tests run at max. 180V;
6. Very small and lightweight (＜9kg/19.8lbs), easy to transport for on-site testing;
7. The CT analyzer has a professional pull box design that is easy to carry and resistant to vibration.
