Zi
  • isloatsiooniseadme kogutakistus seiratava süsteemi klemmide ja maa vahel, mõõdetuna nimisagedusel
  • total impedance of the insulation monitoring device between the terminals to the system being monitored and earth, measured at the nominal frequency fn
  • measure of the opposition to current flow (impedance), both static (resistance) and dynamic (reactance), into the load network being connected that is internal to the electrical source
kogusisetakistus preferred
Usage examples
  • Tingimus, milles komponendi või vooluahela takistus on võrdne allika kogusisetakistusega või ülekandeliini kogusisetakistusega, tagab maksimaalse energiaülekande allikatest koormusele, minimaalse peegelduse ja minimaalse moonutuse.

Zi symbol
internal impedance
Usage examples
  • The condition in which the impedance of a component or circuit is equal to the internal impedance of the source or the surge impedance of a transmission line, thereby giving maximum transfer of energy from sources to load, minimum reflection, and minimum distortion.
