3 Phase Delta Formula
The following equation is used to calculate the power in a 3-phase delta system.
P = \sqrt{3} \times V \times I- Where P is the power (W)
- V is the line voltage (V)
- I is the line current (A)
To calculate the missing parameter, rearrange the formula to isolate the unknown variable.
What is a 3 Phase Delta Calculator?
Definition:
A 3 Phase Delta Calculator is a tool that computes the missing electrical parameter in a 3-phase delta system by applying the standard formula relating power, voltage, and current.
How to Calculate 3 Phase Delta Values?
Example Problem:
The following example outlines the steps and information needed to calculate the missing electrical parameter using the 3 phase delta formula.
First, determine which parameter is missing; in this example, the power value is omitted.
Next, identify the known values; in this example, the line voltage is 400 V and the line current is 10 A.
Finally, calculate the missing power using the formula above:
P = √3 × 400 × 10
P = √3 × 4000
P ≈ 6928.2032 W
FAQ
What does the 3 Phase Delta Calculator compute?
It calculates the missing electrical parameter (line voltage, line current, or power) in a 3-phase delta system based on the provided values and the formula.
Can this calculator be used for both delta and wye systems?
No, this calculator is specifically designed for 3-phase delta configurations; calculations for wye systems involve different formulas.
What precautions should I take when using the calculator?
Ensure that you enter numeric values, leave one field empty for calculation, and avoid entering zero for values in denominators to prevent errors.
