【Abstract】 This paper discussed the Visual Basic 6.0 applied in the short circuit testing lab as a sharpen tool for help the test engineer to select the resistance and reactance value used in the main testing circuit for adjusting the test current and power factor, and these parameters have to meet the requirement of test standards, such as the IEC standard or National standard. This software was applied in a Power Testing Lab. The engineers are very satisfied with performance of this friendly and clearly interface of this application software. They used it to make the calibration test and short circuit test, and this application software shorten their test schedule effectively.更多还原
