1. What is All Day Efficiency?

All Day Efficiency is the ratio of output energy to input energy of a transformer over a 24-hour period. It provides a comprehensive measure of the transformer's performance throughout an entire day of operation, accounting for varying load conditions.

2. How Does the Calculator Work?

The calculator uses the All Day Efficiency formula:

Where:

• \( E_{out} \) — Output energy delivered by the transformer (Joule)
• \( E_{in} \) — Input energy supplied to the transformer (Joule)

Explanation: This formula calculates the percentage efficiency by comparing the useful energy output to the total energy input over a 24-hour period.

3. Importance of All Day Efficiency

Details: All Day Efficiency is crucial for evaluating transformer performance in real-world operating conditions. It helps in assessing energy losses, determining operational costs, and making informed decisions about transformer selection and maintenance.

4. Using the Calculator

Tips: Enter both output energy and input energy values in Joule. Ensure that output energy is less than or equal to input energy for valid results. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is All Day Efficiency important for transformers?
