Flexible configuration: The built-in voltage booster can raise voltage up to 1000V; the built-in current booster can raise current up to 600A; additionally, an external current booster can be optionally configured, connected to the main unit through a primary current interface, with a maximum measurement current of 1500A, meeting the testing requirements of more CTs.
Product Overview:
It is a multifunctional field test instrument specially designed for testing transformers: volt-ampere characteristics, transformation ratio, polarity, error curves, calculating knee points, and secondary side loop inspection, 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 transformer's volt-ampere characteristic curve or transformation ratio, polarity, and other test results. It supports data storage and on-site printing, not only saving tedious labor such as manual voltage adjustment, manual recording, and curve plotting, but also allowing test data to be uploaded to a computer via USB interface for editing, saving, or printing. Simple and convenient operation improves work efficiency, making it a high-cost-performance high-tech product.
