This white paper is intended to explain the contents of the relevant standards for electrical power calculation. First, typical requirements for a universal power theory are derived. Based on these criteria, the so-called FBD power analysis, which serves as the basis for the DIN 40110 standard, is explained in detail as a reference. In this context, typical terms such as instantaneous, active, reactive, non-active and apparent power are defined, explained and visualized using selected examples. In the final section, the similarities and differences between the standards IEEE 1459-2010 Std and DIN 40110-2 are presented.
Key Takeaways:
- Electrical power theory
- Standards for electrical power calculation
- Instantaneous, active, reactive, non-active and apparent power
- DIN 40110 and IEEE 1459-2010 Std
