An intercomparison of the calibration systems for instrument transformers between the Korea Research Institute of Standards and Science (KRISS) and the National Research Council of Canada (NRC), with many different ratios at 60 Hz, was performed using six portable transfer standards. The portable transfer standards consist of two current transformers (CTs) with current ratios of 5 A/5 A up to 20 000...
An overview of the development of a current-comparator-based high-voltage inductance bridge at the National Research Council of Canada (NRC) for the accurate measurements of load losses of large high voltage inductive loads at low power factor operating conditions, such as, large high voltage power transformers and shunt reactors, will be presented. The bridge has ratio uncertainties of less than...
An intercomparison of calibration systems for ac shunt up to audio frequencies between the National Research Council of Canada, Japan Electric Meters Inspection Corporation, and the National Institute of Standards and Technology, U.S.A., is presented. The transfer standard used for the intercomparison is a 10 A, 0.1 shunt
A binary type self calibrateable AC current comparator (CC) was developed at NMIJ. In order to confirm the reliability of the new AC current ratio standard at NMIJ, a bilateral comparison was conducted with NRC using an error compensating current transformer. The paper describes an error estimating procedure for the CC and the results of the bilateral comparison
