CTTX2™ & CTTX5™
Current Transformer Testers
The CTTx2™ & CTTx5™ are rugged and easy to use current transformer testers, that offer automatic & manual testing modes. These instruments are designed to deliver fast and reliable measurements.
The CTT™ will test the current transformer ratio, phase shift, polarity, excitation, saturation, winding resistance and insulation resistance using the voltage method in compliance with ANSI/IEEE C57.13.1 & IEC 60044-1 standards, where voltage is applied to the secondary X terminals of the current transformer. The CTT™ burden test injects a current into the secondary loop to verify the integrity of the current circuit and to determine its impedance & VA. This information is required to insure the CT™ will perform under all circumstances. The CTT™ can also test the ratio, polarity, phase shift, winding resistance & insulation resistance of voltage transformers.
