The OMICRON CT Analyzer Current Transformer Tester automatically determines all relevant current transformer values and compares the results with the selected standard. The OMICRON CT Analyzer is complies with the o IEC 60044-1, IEC 61869-2, and IEEE C57.13 (up to accuracy class ≥ 0.3). The unit guarantees 0.05% current accuracy at the ratio between 1 to 2000 and 3 minutes phase displacement accuracy (1 min when calibrating on site).
The CT Analyzer Current Transformer Tester allows all types of single and multi-ratio current transformers to be tested on-site. Manufacturers of current transformers, high voltage transformers, and switchgear also use the CT Analyzer for tests during development and production. The OMICRON CT Analyzer can be paired with the CT SB2 switch box available as an accessory for automated testing.
