User manual for the Musen MS-601G instrument that tests CT and PT characteristics with high accuracy and automation.
The MS-601G is a high‑performance testing instrument for current transformers (CT) and voltage transformers (PT). It provides comprehensive tests such as excitation (V‑I) characteristics, ratio, polarity, secondary winding resistance, load, ratio error and phase error, meeting standards like GB1208 and IEC60044‑1. The device uses a DSP and ARM processor, stores up to 2000 test sets, and generates Word reports via PC software.
The manual covers safety precautions, installation, panel description, parameter settings, test procedures for CT and PT, result interpretation, and wiring diagrams for various transformer configurations. It also includes an appendix with low‑frequency test theory and error‑curve calculations. This manual is written in Chinese.
