  • trafoühendusega arvesti korral on selleks voolu väärtus, millele arvesti on projekteeritud
  • voolu väärtus, mille kohaselt on trafoga käitatava mõõtevahendi või arvesti asjakohane toimivus fikseeritud
  • voolu väärtus, mille juures on määratletud välise voolutajuriga töötava energiatarbimise mõõte- ja jälgimisseadme spetsifikatsioon
  • in case of a transformer operated meter, the value of the current for which the meter has been designed
  • value of current in accordance with which the relevant performance of a transformer operated meter is fixed
  • value of the current at which the specification of a PMD operated by an external current sensor is defined
  • curren assigned by the manufacturer for the specified operting condition of the measuring equipment
nimivool preferred
Usage examples
  • Trafoühendusega arvestite korral on terminid "tugivool" ja "nimivool" sünonüümid.
  • Nimivool on maksimaalne püsiv elektrivool, mille korral kaitse veel ei rakendu.
Good to know
  • Vooluringis ohutult voolava voolu suurim väärtus on nimivool, mille ületamisel kas traat sulab või on muid probleeme.
tunnusvool
Usage examples
  • Tunnusvool on mõõtevahendi vool ettenähtud oludes.

Usage examples
  • In case of transformer operated meters, the terms "reference current" and "rated current" are synonymous.
Good to know
  • The rated current is that current for which the equipment or the machine has been designed.
