Application

Insulation resistance meter with adjustable testing voltage - up to 5 kV. It is a great tool for assessing the condition of electrical insulation in residential buildings, industry, railways and other facilities of general use. Due to its parameters - excellent performance, low power consumption from batteries, the option of charging them during measurements, convenience of use and a  high ingress protection level - it is perfect for maintenance teams, testing motors, cables, street lighting or at the construction and maintenance of  photovoltaic systems. The meter may be recommended to installers working on telecommunications and electric power systems that require the inspection of the insulation sleeve/sheath resistance (UN ≤ 30 kV) to the voltage of 5 kV applied for 5 minutes.

Features

The meter may be used to measure the insulation resistance using the adjustable test voltage up to 5000 V. When testing the cables, it automatically discharges their load at the moment of completing the measurement.

MIC-5001 allows the user to determine the insulation resistance by applying linearly increasing voltage with the slope of 1 kV/s, according to standard EEE Std 95TM-2002. This functionality is called RampTest.

In contrast the maximum test voltage, this slow and uniform method of applying test voltage protects the insulation against sudden “electrical stress”. This process may reveal defects that cannot be observed in classic RISO resistance measurement. If the tested insulation is weakened or defective, RampTest will enable the user to determine its maximum withstand voltage. In addition, this functionality is particularly useful in testing rotating machines or surge arresters.

The meter has a built-in voltmeter of AC and DC voltages in the range of up to 750 V. Extensive memory allows the device to record and send to a computer nearly 12,000 measurement results. Download Sonel Reader software from manufacturer’s website to analyse the measurement results and present them in graphic form, e.g. current or resistance values shown in a function of time.

Product Details:

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.

With the use of the Sonel MRU-120HD meter it is possible to perform earth resistance measurements using the 3-pole and 4-wire method. The instrument also allows measurements to be made using additional clamps (multiple earthing - without the need to disconnect the monitoring connections) and measurements using the two-clamp method. In some cases, the measurement can be done without the use of auxiliary probes driven into the ground. Sonel MRU-120HD is a tool designed especially for earthing measurements in the power industry. Measuring range (measurements in accordance with EN 61557) from 0.30 Ω.

Other practical functions of the device are the ability to measure the resistivity of the ground and the continuity of protective and equalising connections.

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)
• Data transmission to the computer
• Battery indication

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.
• The graphical user interface provides clear readings and explicit messages. This translates into quick, trouble-free service.

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.
