What Is Apparent Load?
Apparent load refers to the total electrical load imposed on an AC power system, expressed in kilovolt-amperes (kVA). It represents the combined effect of active and reactive power drawn by connected equipment.
Why Apparent Load Matters in EV Infrastructure
Apparent load determines the electrical capacity required to supply EV charging installations. It is used for sizing transformers, cabling, and grid connections.
How Apparent Load Works
Electrical devices draw current and voltage.
Total load includes usable and reactive components
Apparent load reflects overall system demand. and
