Title: Voltage Transformer Calibration System Based on a Digital Current Comparator
Abstract: This paper details the development of the design of a very high accuracy calibration system for voltage transformers based on a current comparator. It digitizes the signals by high precision DMMs, and then those signals are reconstructed. The modulus and phase ratio values are obtained. The current capabilities range from 10 μA to 5 mA with high accuracy. The high and low voltage capacitors are of high accuracy, too.
