The design of on-site calibrator for integrated error of low-voltage measurement device

Energy measurement is an important basis to evaluate Energy utilization and Energy saving effect, but the accuracy of the measurement device affect to the equity. The previous on-site calibrator of low-voltage measurement device is complex to operation, not convenient to carry and has brought great inconvenience, so developing a new generation low-voltage power measurement device field calibrator is inevitable. In this paper, the proposed method of field calibrator is given based on relevant literature and data. Given the field calibrator´s software design, hardware design and given the hardware and software flow diagram Fig. This site calibrator design is emerging, and it is effective.
