CT Analyzer

CT Analyzer

Type: CTA-1000
         The CT analyzer automatically determines all relevant current transformer values and compares the results to the selected criteria. After 10 years of testing and development experience with our technicians, this CT analyzer can evaluate current transformers in accordance with IEC or IEEE standards in just a few seconds with the push of a button.
         It facilitates rapid and economical field testing and calibration of metering and protection current transformers. Current transformers, high voltage transformers and switchgear manufacturers are also testing with CT analyzers during development and production.
