NIM1000 - Impedance meter

  • Measures the grid impedance of the phase and neutral conductor up to the 10th harmonic
  • Triggers load-sensitive and neutral faults
  • Performs multi-phase measurements and switches automatically between the test points
  • Is highly accurate and simple to operate

With up to 1kA test current, the NIM 1000 measures the loop impedance to detect malfunctions in the LV grid at an early stage. The impedance meter triggers load-sensitive and neutral faults, detects weak contacts, and exposes hidden flaws. Depending on the grounding conditions of the tested grid, a multi-phase measurement calculates the impedance of the neutral conductor to detect defects that can cause severe safety issues.
