3 Phase Delta Formula

The following equation is used to calculate the power in a 3-phase delta system.

P = √(3) × V × 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.
