KGHG-E Transformer Comprehensive Apparatus CT PT Comprehensive Characteristic Instrument TTR Machine
Product Introduction
KDHG-A transformer characteristic comprehensive tester is a kind of multifunctional field test instrument specially designed for measuring transformer: volt-ampere characteristic, ratio, polarity, error curve, calculating inflection point and secondary side loop inspection. During the experiment, only need to set the test voltage and current value, and the equipment can automatically boost the voltage/current, and the transformer's volt-ampere characteristic curve or ratio, polarity and other experimental results are quickly displayed, supporting data saving and on-site printing, not only eliminating manual voltage regulation, manual recording, curve tracing and other tedious labor. The test data can also be uploaded to the computer through the USB interface for editing and saving or printing. Simple and convenient operation, improve work efficiency, is a cost-effective high-tech products.
