  • pinge faasijuhi ja maandatud neutraalpunkti vahel maandatud neutraalpunktiga jaotussüsteemides
  • (in distrution systems with an earthed neutral point) voltage between a phase conductor and the earthed neutral point
pinge maa suhtes
Usage examples
  • Elektrijaam tekitab maandatud neutraalpunktiga jaotussüsteemide faasijuhtmes pinge maa suhtes.
U0 symbol
voltage against earth
Usage examples
  • The power plant generates a voltage against earth in the phase conductor of distribution systems with a grounded neutral point.

  • pinge faasijuhtide ja maa vahel, kui üks jaotussüsteemi faasijuhtidest on maaga lühises
  • (in all other distrubution systems) voltage present between the remaining phase conductors and earth when one of the phase conductors is short-circuited to earth
faaside pinge maa suhtes
Usage examples
  • Jaotusvõrgus on lühistatud faaside pinge maa suhtes 0, lühistamata faasis võib aga pinge suureneda 1,5 korda, mis võib ületada isolatsioonile lubatud pinge väärtust.

voltage against earth
Usage examples
  • In a distribution network, the voltage against earth of short-circuited phases relative to ground is 0, but in an unshort-circuited phase, the voltage can increase by 1.5 times, which can exceed the permissible voltage value for the insulation.
