Introduction
The active transformer capacity characteristic tester has a built-in high-energy rechargeable battery, which can accurately measure the capacity, load loss, and determine the type of oil-immersed, dry-type, and various other types of transformers without external power supply. The internal digital synthesis of three-phase standard sine wave signals effectively ensures the accuracy of various test data under non-rated conditions.
