Question

In the design of transformer windings, creepage between conductors and core yokes is prevented by providing:
A. vertical oil ducts
B. keep-back distance
C. bushing terminals
D. separation sticks

Answer 1

In the design of transformer windings, creepage between conductors and core yokes is typically prevented by providing **B. keep-back distance**. This method ensures that there is adequate spacing between the conductors and the core to minimize the risk of arcing or electrical failures due to creepage along the surfaces.
