Testing data collection is done in the warehouse of PT PLN (Persero) UP3 Kebon Jeruk. The test is carried out to determine the current error of each accuracy class. Accuracy class is a number that states the limit of measuring error allowed on a measuring instrument under reference conditions. While the precision / accuracy of the current transformer is stated in the error rate. The smaller the error of a transformer, the higher the level of precision / accuracy. Where the magnitude of this current error will affect the accuracy of the current reading. The results of the accuracy class of CT 0.5 the current error obtained is still within the ± 0.5 error limit. As well as the accuracy class of 0.2S which is ± 0.2. The effect of the replacement of CT accuracy class can be seen from the pull of customer data where the difference in the current has increased, when using class 0.5 in one phase that is equal to 0.692851597 A while in class 0.2S of 0.71118514 A. Therefore by changing the CT accuracy class, the current reading becomes more accurate.} }
