Kokonaistehoa

Kokonaistehoa is a Finnish term that translates roughly to “total power” or “overall power,” and it is used in engineering and energy contexts to describe the complete output or capacity of a system. The term can refer to either the sum of individual power contributions from all components or the maximum capability of a device, installation, or network.

The word combines koko, meaning whole or total, with tehoa, meaning power. Because it is a general descriptor rather than a fixed quantity, the precise meaning of kokonaistehoa varies with context. In electrical engineering, it may denote active power (P), apparent power (S), or the overall rated capacity, depending on the specification being referenced.

Applications of the concept appear in power generation, distribution, and consumption. In a power plant, kokonaistehoa commonly describes the total generation capacity. In electrical installations, it can indicate the combined load that equipment is capable of drawing or delivering. In mechanical or automotive contexts, it may refer to the aggregate output of an engine, motors, and transmission system.

Measurement and interpretation depend on context, because kokonaistehoa is not a single SI quantity. Engineers typically specify related quantities such as real power (watts), apparent power (volt-amperes), and reactive power (var), along with ratings and time characteristics. The term is clarified by accompanying data that state whether it refers to nominal, maximum, or instantaneous total power.
