- Abstract:
- Main characteristic of high accuracy class current transformers is very small amplitude and phase errors (approximately 10 ppm). Such an error is a reason of complexity and sensitiveness of that metrological task. This paper presents a new method for high accuracy class current transformers calibration simultaneously with two different measuring apparatus. The method is presented as well as measuring scheme and calibration results. Estimation of uncertainty of measurement shows that this method has better results than separated calibration methods.
