A $16.,7$KVA,$7200-120V,b0H_2,t_{wa}$ winding transtonmer has the followiths Let modal imeedonces with the $720$ V winding is the primary

$R_c=391,000,x_m=54,800$

$r_1=18\mathrm{.}7,x_1=77\mathrm{.}8,r_2-0\mathrm{.}00519,x_2=0\mathrm{.}0216$

The voltage applied to the primary is adjusted co that of the secradary terminal $120$ V when the load secondary is $16\mathrm{.}67$ kV at unisy pf$.$
