Tests of New MIKO-9 Are In Progress

The MIKO-9 milliohmmeter, a new product of the SKB EP Company, is being subjected to different tests (its manufacture is scheduled for the second quarter of 2018). The instrument is designed for measuring the AC electric resistance in the inductance and inductance-free circuits in the range from 10 mkOhm ÷ 30 kOhm on currents of up to 10A for.

The peculiar feature of the device is integration of special-purpose modes for measuring different objects with account of their specific features: resistive and inductance objects; voltage transformers; current and power transformers; generators, motors, compensators, connection filters, and magnet cores.

The device has been subjected to different tests on the inductance and resistance objects, on a large number of transformers of different types and capacities; therefore, in the middle of February we planned to test the device on the engines and generators. Tests were performed at the production site of OJSC "First non-metallic company", a subsidiary of Angasolka Chipping Mill.

The first stage included works on the DС electric motor DE-818 U2 designed for continuous operation in the electric drive of a materials handling vehicle and a mill table.

At Stage II measured was the electric resistance of the collector contacts in the DС generator.

The device is completed with test cables at Customer’s choice, that allows the test kit to be selected for specific high-voltage equipment (test cables have different length and ‘crocodile’ clamps of different size). The following equipment was involved in the tests: a test kit with ‘crocodile’ clamps with 80 mm jaws and 8.5m cable, and a 3m cable for measuring transient resistances of contact-type connections.

Representatives of the Angasolka Chipping Mill noted small size, ergonomic features of the MIKO-9, availability of an in-built battery, high speed of measurements and friendly interface. The device was subjected to overall tests, demonstrated proper operation and allowed all the objectives to be achieved.

The instrument is currently under tests and pilot operation for being entered into the RF State Registrar of Measurement Instruments. Its manufacture is scheduled for the second quarter of 2018. Orders are accepted.
