Pain Points and Solutions
For global transformer manufacturers, we address core business pain points with targeted solutions as follows:
User Core Pain Point | Exclusive Solution | Direct Value for Users |
|---|---|---|
Repeated manual wiring for DC resistance, turns ratio and other test items, leading to high labor cost and long test cycle | Test trolley one-time wiring for DC resistance and turns ratio tests, automatic data upload to the central test system | Reduce wiring workload by 80%, cut test cycle from hours to minutes, lower requirements for operator experience |
Scattered test data across separate instruments or paper records, difficult to trace and comply with audit requirements | Centralized automatic data recording, tamper-proof report generation, compliant with CNAS/IEC/ISO audit standards | Eliminate manual recording errors, reduce data management workload by 70%, meet international audit requirements |
Large-capacity test equipment is bulky and heavy, difficult to transport and deploy on site | 20-foot or 40-foot container integrated design, meeting international shipping standards, no civil construction required for outdoor deployment | Cut transportation cost by 40%, reduce on-site deployment time to 30 days, lower infrastructure cost by 40% |
All solutions are validated by over 200 global customer deployments.
