6 voltage and current output channel, can test not only traditional relays and protection devices, but also modern micro-computer protection devices, especially for transformer differential protection and standby automatic switching device. This tool is often used in the field during the commissioning and maintenance of complex electrical systems, including transformers, generators, or multi-phase distribution networks.

SFRA stands for Sweep Frequency Response Analysis, and it is a diagnostic test used primarily for transformer condition monitoring. SFRA helps assess the mechanical integrity and winding condition of a transformer by analyzing the frequency response of the transformer at different frequencies.
