短时过电流试验设备的校准方法研究
Research on the calibration of short time over current experiment device
摘要
Abstract
Short time over current effect experiment is significant on testing capability of tolerating instantaneous large current in electrical device, and both on calibrating working performance of smart meters.This paper proposes a novel approach of calibrating the short time over current experiment approach by using current clamp and digital oscilloscope, and describes the method of evaluating measurement uncertainly.This approach, which the calibration precision and uniformity are confirmed through result comparison, can provide important technology base for short time over current effect experiment.关键词
