Testing of current transformers through secondary injection

Benefits of this solution

Complete solution

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.

The CT Analyzer approach

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.

High accuracy and light weight

CT Analyzer’s extremely high accuracy (0.02 % typical) also allows field verifications of CTs up to the 0.1 accuracy class. You can easily carry the lightweight device (< 8 kg / 17.4 lbs) to any test site.

“The CT Analyzer is the optimal device for on-site and laboratory testing of protection and metering current transformers, including tests of the transient behaviour.”
