Pain Points & Solutions
User Core Pain Point | Dedicated Solution | Direct Value for Users |
|---|---|---|
Manual repeated wiring for DC resistance and other tests leads to low efficiency and high labor cost, especially for medium and large capacity transformers | Integrated test trolley enables one-time wiring to complete DC resistance and transformation ratio tests, with automatic data upload to the main test system | Cut test cycle by over 60%, reduce required test personnel by 50% compared to manual testing |
Scattered test data across separate instruments or paper records causes traceability issues and compliance risks for international audits | Centralized data management system automatically records all test data and generates standardized reports, with anti-tamper functionality | Eliminate manual recording errors by 90%, meet CNAS, IEC and ISO audit requirements |
Large capacity test equipment is bulky, difficult to transport and deploy on site, requiring long civil construction cycles | Containerized design (20ft for 5000kVA models, 40ft for 10000-30000kVA models) meets ocean shipping standards, no civil construction required for outdoor deployment | Reduce infrastructure cost by over 40%, shorten on-site deployment time to 30 days |
