Overview
The SXFA Series analyzer performs automated testing on protection- and metering-class CT/PT characteristics, suitable for both laboratory and field applications. Compliant with GB1207, GB1208, GB16847 (IEC60044-1, IEC60044-6), and other standards, it streamlines testing workflows by eliminating manual voltage adjustment, data recording, and curve plotting. Equipped with a built-in high-speed thermal printer, it supports on-site report printing and data storage. USB connectivity enables seamless data transfer for further analysis and documentation, enhancing operational efficiency and ease of use.
