Product Introduction

CTA-1000 Series CT Analyzer automatically determines all relevant current transformer values and compares the results with the selected standard, include excitation data, saturation inflection point, remanence coefficient， accuracy limit overcurrent factor, ratio and error data. The device evaluates the current transformer as per the IEC or IEEE standard within seconds with the push of a button.

It facilitates fast and economical on-site testing and calibration of metering and protection current transformers. Manufacturers of current transformers, high voltage transformers and switchgear also use the CT Analyzer for tests during development and production.
