Megger Seba NIM1000 Loop Impedance Tester measures network impedance

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. Given the complexity of the measurements the NIM1000 is capable of making it remains easy to use. It can measure current capacity under real life conditions, determine voltage dips from given loads and perform tests on cables, supply lines and busbars.


 

Megger NIM1000 Key Features:

  • High test current up to 1000 A
  • Single or three-phased measurements
  • 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
  • Display of all measured parameters
  • Tests in accordance with DIN EN 61557-3; VDE 0413-3
  • Is highly accurate and simple to operate
