Megger NIM1000-IMPEDANCE METER

With a test current of up to 1 kA the NIM1000 measures the network impedance of the phase and neutral conductors to the 10th harmonic. It highlights load-sensitive and neutral faults, detects poor contacts and unseen problems. It is also useful for measuring the earth loop impedance close to the source of supply.

Megger NIM1000-IMPEDANCE METER specifications:

• Test Current Range:80 to 1000A (adjustable)
• Maximum Current (peak) imax (depends on the grid impedance):≤ 1000 A @ 400 V
  ≤ 600 A @ 230 V
  ≤ 300 A @ 115 V
• Test Parameters: Z = Impedance (value and phase)
  R = Resistance (real part)
  X = Reactance (imaginary part)
  ZPEN = Impedance value PEN (calculated)
  Z, R, X und ZPEN are displayed for the power frequency up to the
  10th harmonic (phase-N, phase-phase)
  Urms = RMS voltage
  Imax = max. test current
  Is = Short circuit current
  Skv = Continuous short circuit power
  f = Net frequency
  VD = Voltage drop at nominal connected power (in %)
  Pmax = max. connected power at nominal voltage drop
• Input Voltage (Serves as Supply Voltage):90 V … 480 V, 50/60 Hz (at test clamps)
  90 V … 230 V, 50/60 Hz (at power outlet)
