HDHG intelligent transformer tester, is a special test transformer: volt-ampere characteristic ratio, polarity, the error curve, angle difference than the difference to calculate the multi-functional site of the inflection point and the secondary circuit check test instrument. Only set the test voltage / current value of equipment in the experiment will be able to automatically boost / l stream, and the transformer volt-ampere characteristic curve or variable, polarity experimental results show up quickly, support for data retention and on-site printing not only eliminates the need for the tedious labor of manual pressure regulator, manual record, describe curves, but also through the USB interface test data uploaded to the computer to edit save or print. Easy to operate, and improve work efficiency is a cost-effective high-tech products. 
 The main functions and features: 
 , Safe and reliable: domestic first MBC power control technology, single-phase AC220V input power, and the sharing of power and power supply input port, more scientific and rational design, the use of more secure and reliable. 
 Second, in line with national maintenance of order 
 3, the output capacity: 
 Stand-alone 220V input voltage output 0-1000V, the largest single current output of 0-600A is ideal for field service use. 
 Fourth, the fully functional: 
 Detection of CT / PT voltage characteristics, ratio, polarity, 5% and 10% error curve, the angle difference than the difference of CT is the first flow passage and CT demagnetization, easy use of a machine. 
 Fifth, the wiring 
 6, the test range
