Nanke Electric vs. Traditional Testing Mode: Core Technological Advantages I. Core Operating Mode: From “Repeated Wiring” to “Fully Automated Single-Wiring” 1. Nanke Electric’s testing mode: Only one wiring is required, and with a single button press, seven factory routine tests can be automatically completed. The entire process achieves automatic control, automatic testing, and automatic report generation. 2. Traditional testing mode: Each test item requires manual replacement of test clamps, involving at least ten wiring operations. The entire process relies on manual operation, manual judgment, and manual recording, making the procedure cumbersome and inefficient. II. Efficiency and Labor: Quantitative Cost Reduction and Efficiency Improvement 1. Testing efficiency: Compared with the traditional mode, the testing time is reduced by 70%, significantly shortening the transformer factory testing cycle and aligning with the pace of mass production. 2. Labor costs: Only one tester is nee
