Description
A calibration system for instrument transformers, based on the comparison method, has been established at SASO NMCC. Ratio error and phase displacement measurements are performed by using the calibration system up to 4000 A for current transformers and up to 36 kV for voltage transformers at 60 Hz. Calibration uncertainties for both current and voltage transformers are well below the industrial and metrological needs in the country. Bilateral comparisons between SASO NMCC and TUBITAK UME have been performed in order to evaluate the performance of the calibration system.
