Tap Voltage Formula
The following formula is used to calculate the Tap Voltage.
Vt = Vs * (1 + T/100)
Variables:
- Where Vt is the Tap Voltage (volts)
- T is the tap up percentage (%)
- Vs is the secondary voltage (volts)
To calculate the Tap Voltage, multiply the secondary voltage by (1 + tap up percentage / 100).
How to Calculate Tap Voltage?
The following two example problems outline how to calculate the Tap Voltage.
Example Problem #1:
- First, determine the tap up percentage (%). In this example, the tap up percentage (%) is measured to be 50.
- Next, determine the secondary voltage (volts). For this problem, the secondary voltage (volts) is calculated to be 4.
- Finally, calculate the Tap Voltage using the formula above:
Vt = Vs * (1 + T/100)
Inserting the values from above and solving the equation with the input values gives:
Vt = 4 * (1 + 50/100) = 6 (volts)
Example Problem #2:
Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:
tap up percentage (%) = 5
secondary voltage (volts) = 60
Entering these values into the formula or calculator above gives us:
Vt = 60 * (1 + 5/100) = 63 (volts)
