What is the formula for the inside diameter of the low voltage windings?

A. inside diameter = diameter of the circumscribing circle + pressboard thickness insulation between l.v winding and core
B. inside diameter = diameter of the circumscribing circle – pressboard thickness insulation between l.v winding and core
C. inside diameter = diameter of the circumscribing circle + 2*pressboard thickness insulation between l.v winding and core
D. inside diameter = diameter of the circumscribing circle – 2* pressboard thickness insulation between l.v winding and core
Answer» D. inside diameter = diameter of the circumscribing circle – 2* pressboard thickness insulation between l.v winding and core
