Shell-Type Magnetic Circuits of ØË, ØËÏ, ØËÐ, ØËÌ, ØËÎ Types
Winding in shell-type magnetic circuit is placed on the central rod; this simplifies the construction and enables to use aperture better, and provides winding protection from mechanical effects partially. Disadvantage of transformers with shell-type magnetic circuit is oversensitivity to low frequency magnetic field effect. This limits application of shell-type magnetic circuits for input transformers.
