KDZD8313 is a portable transformer capacity tester with a built-in high-capacity lithium battery supporting over 500 tests per charge. It features an internal three-phase precision 50Hz sine wave power supply. With a 7-inch sunlight-readable LCD screen and intuitive menu operation, it accurately measures capacity (10kVA-100,000kVA), impedance voltage, and load loss with an accuracy of 0.2%. The device is compact, weighing only 2kg, and features comprehensive protection functions, dual storage, and thermal printing capabilities.
