When the winding c-d of the single-phase, 50 Hz, two winding transformer is supplied from an AC current source of frequency 50 Hz, the rated voltage of 200 V (rms), 50 Hz is obtained at the open-circuited terminals a-b. The cross sectional area of the core is 500 mm

and the average core length traversed by the mutual flux is 500 mm. The maximum allowable flux density in the core is

Wb/m

and the relative permeability of the core material is 5000. The leakage impedance of the winding a-b and winding c-d at 50 Hz are

and

, respectively. Considering the magnetizing characteristics to be linear and neglecting core loss, the self-inductance of the winding a-b in millihenry is __________ (Round off to 1 decimal place).
