The Sonel MIC-10k1 insulation resistance meter is suitable for comprehensive diagnostic tasks. It measures the insulation resistance of various electrical power devices, including single- and multi-core cables, transformers, motors, generators, capacitors, circuit breakers, and other critical power station equipment.
The MIC-10k1 can generate test voltages up to 10 kV and deliver a current of 6 mA, enabling measurements of up to 40 TΩ. The three-wire measurement system uses a GUARD wire and eliminates surface leakage currents.
The MIC-10k1 also measures the temperature of the tested object and offers key diagnostic indicators. The indicators include the Dielectric Absorption Ratio (DAR), Polarization Index (PI), and Dielectric Discharge (DD). It also has a Step Voltage (SV) method for progressive voltage application.
The MIC-10k1 supports the AutoISO-5000 adapter, has a powerful 60 W inverter, and pinpoints cable faults by intensifying damaged areas. It has built-in digital filters with selectable averaging times (10 to 200 seconds), a backlit graphical screen, and integrates with Sonel Reader software and a mobile app.
