Description

Multifunctional earthing resistance meter

With the use of the presented earth resistance and soil resistivity meter Sonel MRU-120 it is possible to carry out earth resistance measurements using 3-pole and 4-wire method, measurements with the use of additional clamps (multiple earthing – without the necessity of unfastening the monitoring connections), as well as measurements using two-clamp method – in some cases it is possible to carry out the measurement without the necessity of using auxiliary probes driven into the ground. Sonel MRU-120 is a device designed to meet the needs of the power industry and used for earthing measurements – measuring range (measurements in accordance with EN 61557 standard) from 0.30 Ω. The functionality of the device is completed by the possibility to measure the resistivity of soil and the continuity of protective and equalising connections.

Application

MRU-120 meter was created for the most difficult working conditions. It generates a measuring current exceeding 200 mA, which provides effective measurements of grounding of energy objects such as transformer stations and power stations.

Thanks to the methods using clamps, it is not necessary to disconnect the control connectors, which is sometimes a very tedious operation. This plays a special role when performing works on objects exposed to weather conditions, where the connecting elements are sometimes corroded or tarnished. The graphical user interface provides clear readings and explicit messages. This translates into quick, trouble-free service.

Protection and equipment

Housing of MRU-120 ensures safe operation in field conditions and inside buildings. Ingress protection rating of IP54 protects the device against water and solids in case of splashes or dusty conditions. Moreover, the design of the device provides very good protection during transport and handling. Extensive standard equipment allows user to perform most measurements without the need to purchase additional accessories. MRU-120 is a versatile solution that offers comprehensive testing of earthing systems.

Capabilities

The measuring methods available in the device allow for comprehensive control of working and protective grounding. The calibration function of the test leads eliminates the influence of their resistance on the result. However, this is just the beginning.

  • The four-lead method provides very accurate measurement of the expected small values of resistance – eliminates the resistance of the test leads connecting the meter to grounding.
  • Measurement of the continuity of protective connections and equipotential bonding’s with a current exceeding 200 mA meets the requirements of EN 61557-4 standard.
  • Before performing the measurement, the meter checks whether the tested object is a subject to excessive interference voltage, which may indicate additional problems.
