Abstract :
This paper grades several three-phase combinations of instrument transformers and watthour meters under various conditions according to their approach to the best standard practice. The combinations are described and sources of uncertainty or of error are discussed. Diagrams are included to show the schematic connections of the component transformers and meters, both separately and in combination and of the power systems to be metered.
