equation expresses the relation: BD = BC^+CD 207 64 DESIGN OF SMALL TRANSFORMERS Substituting the numerical value 3.72 for BC and CD gives BD^= 3.722+3.722 = 13.76+13.76 =27.52BD =V27.52=5.2in. In order to provide for sufficient clearance, the diameter of a single turn of the primary should be made… … 4 Fig. 40. Determining Diameter of Circular Turn of Primary Wire there are a total of 154 turns, the total length of the primarywinding will be 221.76 feet, or practically 222 feet. Size of Primary Wire. The size of the primary wire may bedetermined from the well-known relation between the length…
