Resumen
The development and testing of a current comparator (CC) is described. It is intended for ac low frequency applications, such as calibration of instrument current transformers (CT). The CC can be self-calibrated comparing its different inputs between them, without need of an external reference standard. This device was developed to sustain the selftraceability of calibration of CT at UTE (delegated National Metrology Institute of Uruguay).
