Terminal Voltage for DC Shunt Generator Calculator

Calculate Terminal Voltage







Formula

The formula to calculate Terminal Voltage is:

\[ V_t = V_a - I_a \cdot R_a \]

Definition

Terminal Voltage, electric pressure or electric tension is the difference in electric potential between two points in electrical machines. Armature Voltage is defined as the voltage developed at the terminals of the armature winding of an AC or DC machine during the generation of power. Armature Current is defined as the current developed in the armature of an electrical DC generator due to the movement of the rotor. Armature Resistance is the ohmic resistance of the copper winding wires plus the brush resistance in an electrical generator.

Example Calculation

Let's assume the following values:

Using the formula:

\[ V_t = 200 - 1.7 \cdot 35.25 \approx 140.075 \]

The Terminal Voltage is approximately 140.075 Volt.
