znamionowa

Znamionowa is the feminine form of the Polish adjective znamionowy, used in technical and engineering language to denote the nominal or rated value of a quantity. It refers to the value that equipment or systems are designed to operate at under normal conditions and serves as a reference point in specifications, measurements, and comparisons. The term is commonly found in datasheets and standards, with nouns such as napięcie znamionowe (nominal voltage), prąd znamionowy (rated current), moc znamionowa (nominal power), and częstotliwość znamionowa (nominal frequency).

Examples include napięcie znamionowe 230 V, prąd znamionowy 16 A, moc znamionowa 1000 W, and częstotliwość znamionowa 50 Hz. The nominal value may differ from actual measured values due to manufacturing tolerances, temperature, aging, and operating conditions; the difference is described by tolerance or regulation. In standardization, znamionowa is used to specify the product’s intended operating point and is not necessarily the maximum or minimum value.

The term is often used interchangeably with wartość znamionowa or wartość nominalna when describing electrical or physical characteristics of equipment such as transformers, motors, power supplies, and cables. In practice, it distinguishes typical operating conditions and design specifications from extreme limits, guiding design, testing, and compliance processes.
