Sonel MIC-10k1 Isolationswiderstandsmessgerät

The Sonel MIC-10k1 is one of the most modern devices for insulation resistance measurement on the market. Developed for professional users in power supply and industry, this test device offers maximum measurement accuracy up to 40 TΩ as well as extensive diagnostic functions for electrical equipment.

Ideal for:

• Transformers, generators, motors

• Capacitors, single- and multi-core cables

• Switchgear and other high-voltage equipment

• Use in EMC-stressed environments such as substations (up to 765 kV)

Features at a glance

• Insulation measurement up to 40 TΩ with adjustable test voltage:
  50–1000 V (in 10 V steps), 1–10 kV (in 25 V steps)

• PI, DAR, DD, SV tests for comprehensive insulation assessment

• Test current selection: 1.2 mA / 3 mA / 6 mA

• Capacitance measurement, temperature measurement (with probe), burn detection for cable faults

• 2- and 3-wire measurement (with GUARD function for surface leakage current suppression)

• Automatic discharge of the test object after measurement

• Digital filter function (10–200 s & smart), high measurement stability even under strong interference

• Long-term measurement with time control (T1–T3) for assessing absorption behavior

• Voltage and current display during testing

• Measurement on live objects also protected

Intelligent analysis & data processing

With the graphical display, the user can observe resistance, current and voltage curves in real time. This significantly facilitates the assessment of the insulation condition.
The time-dependent display shows immediate deviations and allows precise tracking of insulation problems.

• Integrated memory, app connection & Sonel Reader software for evaluation and logging

• Ideal for long-term monitoring and preventive maintenance

Extended functions with AutoISO-5000

In combination with the AutoISO-5000 adapter, multi-core cables – for example in street lighting systems – can be tested particularly efficiently. When troubleshooting cable systems, the MIC-10k1 enables targeted “burning” of insulation defects with its output of almost 60 W, which can then be located using TDR (e.g. Sonel TDR-420).

Conclusion

The Sonel MIC-10k1 is the first choice for experts in power supply, maintenance and industry who work with the highest test voltages, strong interference and complex diagnostics. Robust, precise and well-equipped for all challenges of high-voltage testing.
