tilavirta

Tilavirta is a Finnish term used in electronics and control engineering to describe the current associated with an operating state of a circuit or system. The word is formed from tila meaning state or condition and virta meaning current.

Context and usage: In Finnish technical writing, tilavirta refers to the current that remains once a system has settled into its commanded state, as opposed to transient currents that occur during switching or startup. The exact interpretation can vary by author; some use tilavirta more narrowly to mean the average current during steady operation, while others treat it as the current trajectory toward a steady-state value.

Relation to other terms: It is related to steady-state current and direct current (tasavirta) but is not an officially standardized term in international engineering nomenclature.

Measurement and analysis: Tilavirta is typically determined from current measurement sensors in conjunction with control signals, and used in evaluating regulation performance, efficiency, and thermal load.
