For … WebMay 31, 2011 · Since the reactor impedance is represented in per unit (percentage) then there is an MVA rating envolved. I need to know what is that value so that I can convert the percentage impedance to my Base. @ThePunisher: I think you did a mistake by multiplying the value by 3 because the 4.16KV is line-to-line. tstc chancellorWebEach saturable reactor’s impedance is determined by the application of DC power to a control winding. As the level of power supplied to the control winding is increased, the saturable reactor becomes more saturated. This reduces the impedance of the AC gate winding, and increase the amount of the supply voltage that is transferred to the load. tstc cengage
