| Abstract |
Standard current transformer(CT) with the nominal ratio errors in the range of - 10 % to + 10 % has been developed. Linearity of the CT ratio error measuring system (CT comparator) has been tested by using wide ratio error standard current transformer(WRE CT). The developed WRE CT can be used to evaluate the linearity of the CT comparator by comparing both the theoretical values and experimental values of the WRE CT. The developed method has been successfully applied for calibration and correction in the CT comparator belonging to industry. |
