CT Performance Measurement

Current transformers integrated in GIS can be difficult to test as they are sealed within its steel housing. Nevertheless, a number of measurements should be made in order to determine the magnetization characteristic, the saturation behavior (ALF/FS), the transformation ratio, the accuracy, the polarity, the load, the winding resistance, the withstand voltage and the remanence.

이 솔루션의 이점

IEEE and IEC conform testing

The CT Analyzer is the most complete and easy-to-use test system for protection and metering CTs according to IEEE and IEC standards. It combines the highest safety standards with CT test and assessment features.

Secondary Injection

Using the indirect test method, a voltage signal is injected into the secondary winding and the CT parameters are measured. Based on the results, the CT’s performance characteristics are calculated.

Assessment of CT Performance

All parameters of single- and multi-ratio CTs (ratio, phase, excitation, resistance, ALF/FS) are determined within minutes. The CT assessment automatically delivers an immediate "good / bad" evaluation.
