A FLUX-BALANCE CURRENT TRANSFORMER CORE FIGURE 1 The ratio of a CT’s primary rating to its secondary rating is equal to the number of secondary turns. For example, a CT with a 5-A secondary and 20 turns will have a nameplate ratio of 100:5. This ratio is based on the primary conductor passing once through the transformer window. If multiple primary turns are used, the ratio will be reduced
