Voltage Rise Calculator

Formula

The formula to calculate the Voltage Rise (Vr) is:

\[ Vr = \frac{L \times I \times Vd}{1000} \]

Where:

\(Vr\) is the voltage rise (volts)
\(L\) is the cable length (meters)
\(I\) is the current (amps)
\(Vd\) is the voltage drop per ampere meter (V/amp-m)

What is Voltage Rise?

Voltage rise is the increase in voltage observed in an electrical system, typically caused by the inductive properties of the system when current flows through it. It is an important parameter in electrical engineering to ensure that the voltage remains within acceptable limits and that the system operates efficiently. Voltage rise can impact the performance and safety of electrical systems, making its calculation crucial in design and analysis.

Example Calculation

Let's assume the following values:

Cable Length (L) = 100 meters
Current (I) = 10 amps
Voltage Drop per Ampere Meter (Vd) = 0.05 V/amp-m

Using the formula to calculate the Voltage Rise (Vr):

\[ Vr = \frac{L \times I \times Vd}{1000} = \frac{100 \times 10 \times 0.05}{1000} = 0.5 \text{ volts} \]

The Voltage Rise (Vr) is 0.5 volts.
