DTTS
DTTS (Distribution Transformer Test System) is designed for efficient and standardized testing of distribution transformers in manufacturing and quality-control environments. By integrating test power, measurement, automatic switching, control and data processing into one coordinated platform, the system simplifies the testing workflow and reduces repetitive manual operations. It is particularly suitable for continuous and batch testing, helping manufacturers improve test efficiency, consistency and overall production quality.
