Executive Summary

The CT Ratio data item (J0454) is defined in the DTC as the ratio of the primary and secondary currents with an example value of 1500/5. However 28,322 of the 32224 (88%) CT Ratios we have on our portfolio do not confirm to this example and appear to be ‘invalid’ entries. A table of ‘invalid’ entries by volume and volume by MAP are appended to this document. We have also seen this to a lesser extent with VT Ratios.
