simon says

30Kva=30,000va

30,000 VA=440V*68.1818 Amp*1 (Pf)

Hense Ka=0.068 Wrong



Simon if you look at the post, the voltage is 380 volt and
not 440 volts as you posted. Also you incorrectly forgot to

use 1.73 when working with 3 phase voltage.

hai...... tis is Hemanth. jst now completed electrical engineering... i wanna to apper for ap tranco exam... plzz send me the previous q's paper link......thanx in advance.
