The Design and Application of Automatic Transformer Calibrator Overall Test System
A design of computer-controlled automatic transformer calibrator overall test system is proposed.The device is composed of computer,automatic transformer calibrator overall test device,standard communication protocols and other components.The controller of computer hardware is DSP processing chip TMS320LF2407A.The interactive interface of software part is friendly and intuitive virtual instrument software.Meanwhile,the system also uses high-precision numerical control linear frequency AC transformer power supply as the test signal power.The use of the prototype of automatic transformer calibrator overall test system is in good condition in EPRI.The efficiency is greatly improved.
