TRUE RMS earth measuring clamp for earth loop resistance and leakage current measurement

Measuring functions:

  • earth loop resistance measurement RE in multiply earthed earthing systems
  • measurement of leakage and load currents from 0.3 mA to 35 A using the TRUE RMS measuring method

Features:

  • precise due to TRUE RMS measuring method (AC, AC+DC)
  • optical and acoustic alarm function in case of excessive earthing resistances
  • large measuring clamp diameter of 38 mm
  • memory of measured values/data logger for 116 measurements
  • automatic calibration during start-up
  • measuring category CAT III 300 V
  • supplied in a hard-top case and with reference resistance loop

Functional principle:

  • The measuring clamp has an excitation winding and a sensor winding.
  • The excitation winding induces a current flow in the clamped earthing conductor via a constant AC voltage U (f = 3.333 kHz).
  • The sensor winding measures the induced current flow.
  • The BENNING CM E1 measures (calculates) the resistance of the entire earth loop Rs = U / I.

Advantage of earth resistance measurement without using rods:

  • no need to disconnect the earthing conductor (often difficult because of corrosion)
  • no need to install probes/auxiliary earth electrodes
  • quick and easy measurement
  • safe both for the testing personnel and the electrical installation (earthing is maintained during measurement)
  • no failures of the electrical installation due to disconnection of the earth connection

Typical fields of application:

  • electrical installations with parallel earth connections
  • overhead line networks with pole-type earth electrodes
  • lightning protection systems of buildings
  • street lighting, telecom applications, wind energy
