· Otherwise, we will never know the voltage drop at the motor terminal box. Thirdly, the remaining base load on the bus also needs to be modeled, since this affects the Transformer regulation and the violtage drop. Reply. Jimuel Medina. Sep 17, 2021. I believe this was modeled in a way that the regulation of transformer and its tap were already identified. I think this is something the author of ...

Operation of the Synchronous Motor | electric equipment
The amortisseur winding powers the rotor to 95 to 98 percent of synchronous speed (when AC is applied to the stator of the synchronous motor). As the rotor accelerates, a discharge resistor controls the voltage transformed to the DC field. An AC relay coil (no. 1) is connected across part of the discharge resistor and operates on the voltage drop across this part of the resistor.

What is Synchronous Reactance Synchronous Impedance
· Voltage drop due to armature resistance, IR a. Voltage drop due to synchronous reactance. Armature Resistance : The armature resistance per phase R a causes a voltage drop per phase of IR a which is in phase with the armature current. The armature resistance per phase can be measured directly by voltmeter and ammeter ( ohm's law ) method or by using a wheat stone bridge. .
