The OMICRON CT Analyzer automatically determines all relevant current transformer values and compares the results with the selected standard. 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. The Omicron CT SB2 switch box is available as an accessory to the CT Analyzer for automated testing of current transformers with multiple taps, without the need for complex and time-consuming rewiring.
