WebCardiac size can be estimated by measuring the maximum diameter of the heart and comparing it to the maximum diameter of the thorax; this is the cardiothoracic ratio … WebCurrent Transformer Ratio. Definition: 1) The ratio of primary amps divided by secondary amps. 2) The current ratio provided by the windings of the CT. For example, a CT that is rated to carry 200 Amps in the primary and 5 Amps in the secondary, would have a CT ratio of 200 to 5 or 40:1. Current Transformer Basics and the Current Transformer.
