The Comprehensive Test Instrument for Transformer Characteristics is a multifunctional field test instrument specifically designed for testing transformers: volt-ampere characteristics, transformation ratio, polarity, error curves, calculating knee points, and secondary side loop checks, etc. During the test, only the test voltage and current values need to be set, and the device can automatically boost voltage/current and quickly display the volt-ampere characteristic curve or transformation ratio, polarity, and other test results. It supports data saving and on-site printing, which not only saves tedious labor such as manual voltage adjustment, manual recording, and curve drawing, but also allows test data to be uploaded to a computer via USB interface for editing, saving, or printing. It is simple and convenient to operate, improves work efficiency, and is a high-cost-performance high-tech product.

English Translation: Transformer Characteristics Tester
The Comprehensive Test Instrument for Transformer Characteristics is also known as Transformer Tester, Volt-Ampere Characteristics Comprehensive Tester, Transformer Characteristics Tester, Current and Voltage Transformer Tester, CT Characteristics Tester, PT Characteristics Tester, etc.
The Comprehensive Test Instrument for Transformer Characteristics is specifically designed for relay protection professionals to test current transformer volt-ampere characteristics, transformation ratio testing, and polarity discrimination. It can also be used for transformer polarity discrimination testing. It is a multifunctional test instrument with a high performance-to-price ratio.
This instrument adopts high-efficiency, low-consumption high-quality materials and a specially wound booster. A single-chip microprocessor is used for data acquisition, analysis, and storage. It has a built-in micro printer that can print test data and curves. When measuring CT transformation ratio, it can automatically calculate the ratio value. One person can complete all testing work. This machine has the characteristics of light weight, convenient operation, and unique performance, making it an indispensable instrument for field personnel.
