The 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.

CT Analyzer can also test current transformers in power transformers or gas-insulated switchgear. The CT Analyzer is ideal for this application, as it injects test voltage into the secondary current transformer connection.

Modern designs of protection current transformers according to IEC 60044-6 define the transient performance during an electrical fault, or an auto-reclosure cycle - such as remanence flux and its permissible limits, the time constant with which this flux will decay, and many other parameters. These IEC definitions are integrated into CT Analyzer, enabling the parameters for TPX, TPY and TPZ classes to be directly verified.

Metering current transformers have to accurately transfer system currents to electricity meters. Considering it is in operation 7 days a week, incorrect billing due to an inaccuracy of just one current transformer circuit in a single feeder may lead to significant financial consequences. Therefore, international standards define the accuracy requirements for metering current transformers.

CT Analyzer comprehensively measures all the essential parameters of metering current transformers within a minute. Its low weight of only 8 kilograms or 17 pounds makes using it on-site just as easy and convenient as in laboratories and test fields.

Important parameters of a protection current transformer are its ratio, its excitation curve, the knee point, its winding resistance, and the burden. CT Analyzer determines all relevant current transformer data during a test duration of approximately one minute: it measures the burden of the secondary circuit, the winding resistance and the excitation curve, calculates the accuracy limiting factor for rated and actual burden, determines its ratio, amplitude and phase angle accuracy, and verifies the polarity.

In some applications, current transformers with secondary taps are commonly used. Each tap represents a different number of turns of the winding and therefore a different current transformer ratio. The CT Analyzer Switchbox, a special accessory for CT Analyzer, can be connected to the taps of a multi-ratio current transformer. All tap combinations can then be tested in one test run, automatically and efficiently.

At the very beginning of their lifecycle, during the manufacturing process, current transformers undergo several testing stages. Current transformer manufacturers have to assure the performance data of the products they deliver: The accuracy of amplitude and phase angle, the performance rating described by the accuracy limiting factor or the terminal voltage for protection type current transformers, and the instrument security factor for metering current transformers. For TPX, TPY and TPZ CTs, several additional parameters describe their transient behavior.

The goal of each protection system is safe and selective tripping. Relays are connected to the current transformer’s secondary side and can only make correct trip or no-trip decisions if their input current is correct. Ensuring this is the task of protection current transformers, which must be able to transform currents flowing in generators, transformers, or bus bars. To ensure reliable protection, current transformers must be tested at several stages during their life cycle.

Current transformers are in operation 24/7 and usually remain in use for decades. Proper specification and maintenance of the current transformer is important for operating protection systems safely and reliably and for correct energy metering and billing. IEEE C57.13 and IEC 60044-1 and IEC 60044-6 describe class characteristics of protection and metering current transformers. CT Analyzer allows a complete and precise measurement of all relevant current transformer parameters, for use in laboratories and on site field conditions.
