IΔ
  • rikkevoolujälguri/-seireseadme lüliti peaahelat läbivate voolude vektorite summa efektiivväärtus
  • RMS value of the vector sum of the currents flowing through the main circuit of the residual current device due to an insulation fault
rikkevool
Usage examples
  • Kui mõõtevahendis tekib rikkevool, tähendab see tavaliselt soovimatut voolu, mis põhjustab pärisuunalise juhi kaudu edastatava voolu mittevoolumist läbi tagasivoolujuhi.
IΔ symbol
residual current
Usage examples
  • If a residual current occurs on a device, it usually means that there is an undesirable current path that causes the current supplied through the forward conductor to not flow through the return conductor.
