What is the Current Transformer Analyzer?
The current transformer analyzer is a multifunctional field test instrument specially designed for testing transformers: volt-ampere characteristics, ratio, polarity, error curve, calculation of inflection point and secondary side circuit inspection. In the experiment, only the test voltage and current value need to be set, the device can automatically boost/upflow, and the volt-ampere characteristic curve or ratio, polarity and other experimental results of the transformer can be quickly displayed to support data saving and field printing. It not only saves the tedious labor of manual voltage regulation, manual recording, curve drawing, etc., but also uploads test data to the computer for editing, saving or printing through the USB interface. The operation is simple and convenient, and the work efficiency is improved. It is a high-tech product with high cost performance.
