2. NKE-DTTS-AUTO Series: Semi-automatic series for medium-large capacity transformers (5000kVA-30000kVA), combining test cart wiring for DC resistance/ratio tests and automated execution for other items
3. PTTS-MD-AUTO Series: Modular ultra-high voltage series for 345kV/240MVA transformers, deployed via 5 40-foot containers with 5-month delivery cycle

Design Philosophy: The systems are designed with high precision, efficiency, traceability, and easy deployment in mind, adhering to full-life cycle reliability standards to meet harsh industrial scene requirements.

Technical Principles

Core working principle is based on integrated industrial control and automated process management. The complete workflow includes: 1. One-time wiring connects all test points to the integrated control system; 2. Industrial computer automatically executes pre-set test sequences; 3. High-precision sensors collect data, which is analyzed and compiled into compliant reports.

Core Architecture & Innovative Design
1. Integrated Measurement Module: Equipped with Class 0.01/0.05 precision current/voltage transformers and YOKOGAWA WT500 series power analyzers, ensuring high data accuracy
2. Automation Control Module: One-click operation triggers full test process, eliminating manual intervention and reducing human error
3. Data Management Module: Automatically records and stores data with tamper-proof features, meeting CNAS/IEC/ISO audit requirements

Comparison with Traditional Solutions: Unlike traditional fragmented testing equipment, our systems solve repeated wiring issues (reducing operation time by 80%), eliminate manual data recording errors (data accuracy improved by 99%), and enable containerized transport (deployment time shortened by 70%).
