Result (Copper Power Dissipation in Watts):

Copper power loss is a critical factor in electrical systems where current flow through copper conductors results in energy dissipation. This calculator helps evaluate the copper power dissipation using standard values, providing accurate assessments for design and diagnostics in electrical circuits.

Formula
The formula used to determine copper power dissipation (CPD) is:

CPD = S ÷ 1.695 × (DCP − CCP)

Where:

• S = Cross-sectional area of the conductor (mm²)
• DCP = Design Copper Power (W)
• CCP = Current Copper Power (W)

How to use

1. Input the cross-sectional area of the copper conductor.
2. Enter the design copper power (expected power).
3. Input the current measured copper power.
4. Click the “Calculate” button.
5. The result will show the copper power dissipation.

Example
Suppose a copper wire has a cross-sectional area of 8 mm², a design copper power of 220 W, and a current copper power of 200 W.

Using the formula:
CPD = 8 ÷ 1.695 × (220 − 200)
CPD = 8 ÷ 1.695 × 20 = approx. 94.34 Watts

FAQs
