The KGHG-A Instrument Transformer Comprehensive Tester is a multi-functional field testing instrument specifically designed for testing instrument transformers, including伏安特性(voltage-ampere characteristics), 变比(ratio), 极性(polarity), 误差曲线(error curves), 计算拐点(calculation of inflection points), and 二次侧回路检查(secondary circuit inspection). During experiments, simply set the test voltage and current values, and the device will automatically boost voltage/current, quickly displaying the voltage-ampere characteristic curve or ratio, polarity, and other experimental results of the instrument transformer. It supports data saving and on-site printing, eliminating the cumbersome tasks of manual voltage adjustment, recording, and curve plotting. Furthermore, test data can be uploaded to a computer via a USB interface for further editing, saving, or printing. The operation is simple and convenient, significantly improving work efficiency. This makes it a high-cost-performance, high-tech product.
