= = A 230 kVA, 2300/230 V, 60 Hz, two-winding step-down transformer has the following parameters: RH = 1.2 Q, XH = 3 0, RL = 12 mQ, XL = 30 mq, RcH = 2 ko, XmH = 1.8 ko. The two winding transformer described in (a) above is now wired to operate as a 2300/2530 V boost autotransformer. Determine the voltage regulation and efficiency at rated load when the power factor is 0.8 lagging. Use the equivalent circuit as referred to the primary side of the autotransformer. Repeat of the parametres: RH = 1.212, XH = 31, RL = 12 m2, XL = 30 m2, RcH = 2 ks2, XmH = 1.8 k 2 = = = =
