Heavy-duty earthing and soil resistivity meter

The Sonel MRU-120HD earth resistance and soil resistivity meter is a robust and functional device characterised by particular resistance to difficult working conditions. It is not afraid of dust or mud and performs excellently even in areas where there is an increased risk of splashing.

Measurement methods

• 3-pole and 4-wire method – measurement of earthing systems using auxiliary probes
• 3-pole method with clamp – measurement of earthing systems with multiple earth electrodes
• Two-clamp method – measurement of earthing system when the auxiliary probes cannot be used
• Earth resistivity – Wenner method
• Resistance of earth and compensatory conductors measured using current ≥200 mA with auto-zero function – meets the requirements of EN 61557-4

Additional features

• Outstanding resistance to harsh environmental conditions – the suitcase housing protects against the ingress of dust and water and protects against the effects of falls
• Measurement of resistance of auxiliary electrodes RS and RH
• Measurement of interference voltage
• Measurement in the presence of interference voltage generated by power networks with frequency of 50 Hz or 60 Hz
• Selection of maximum measuring voltage (25 V and 50 V)
• Automatic calculation of soil resistivity in ohm-meters (Ωm) and ohm-feet (Ωft)
• Memory of 990 measurement results (10 banks of 99 cells each)
• Calibration of clamp used
• Real time clock (RTC)

Application

MRU-120HD 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.

Transport and security

It doesn’t matter if you take measurements while wading in the mud or if you act in the sand amongst clouds of dust. The MRU-120HD meter is ready and will not disappoint. IP67 protection degree when the cover is closed ensures dust-tightness and prevents water ingress – even when the housing is immersed briefly! When measuring, the tightness is still high (IP54), providing protection against dust and water splashes from any direction.

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 bondings with a current exceeding 200 mA meets the requirements of EN 61557-4 standard.

• ERP-1
• ERP-1 + FS-2
• ERP-1 + FSX-3

Flexibility in measurements

The SONEL ERP-1 adapter, in combination with meters that can generate measurement current of 200 mA, serves for measuring of resistance of multiple groundings without disconnecting control connection clamps. The  flexible, big diameter coil allows to measure earth resistance of e.g. transmission towers - including lattice poles - without shutting down the power line.

Ergonomic design of the adapter, its convenient housing and simple operation make earth resistance measurements on transmission towers and pylons quick and problem-free. The protection degree of the adapter is IP67, which makes it suitable for operation in muddy and rain conditions.
