Domain metrologymeasuring instruments
  • mõõtetrafo, mis muundab kõrge vahelduvpinge standardmõõtevahenditega mõõdetavaks pingeks, seejuures primaarmähis ühendatakse kõrgepingeahelaga ja sekundaarmähis mõõtevahendi või kaitsereleega
  • trafot, mida võib määratleda kui seadmetrafot, mida kasutatakse pinge muundamiseks suuremast väärtusest madalamaks väärtuseks
  • transformer may be defined as an instrument transformer used for the transformation of voltage from a higher value to the lower value
  • parallel-connected type of instrument transformer
  • instrument transformer in which the secondary voltage, in normal conditions of use, is substantially proportional to the primary voltage and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections
pingetrafo preferred
Usage examples
  • Pingetrafod on konstrueeritud nii, et need kujutavad mõõdetavale toitele tühist koormust ning neil on täpne pingesuhe ja faasisuhe, et võimaldada täpset sekundaarset ühendatud mõõtmist.

voltage transformer preferred
Usage examples
  • Voltage transformers are designed to present a negligible load to the supply being measured and have an accurate voltage ratio and phase relationship to enable accurate secondary connected metering.
