Measurement of transient resistance in the range of 1 ÷ 100 000 µΩ, the error being as low as ± 0.2%

Small-size wrist microohmmeter MIKO-10 is designed for rapid measurement of DC electric resistance of:

  • contacts of HV and automatic circuit breakers, interrupters, connecting devices, breakers, and relays;
  • bolted, welded and brazing joints of wireways and buses;
  • rail fastenings and wheel sets;
  • other devices and machinery.

Its production is scheduled for the first semi year of 2016.  Orders are accepted. 
The instrument is under tests and in pilot operation for being entered into the State Registrar of Measurement Instruments.

Test amperage of up to 10A

The instrument is designed for being applied at electric networks, power plants and substations, traction substations of electric transport, and at industrial enterprises where 10A current is sufficient for measurements.

In case of obvious oxide film on the contacts more powerful microohmmeters are recommended, such as MIKO-21 (current of up to 200A) or MIKO-2.3 (current of up to 1000A), as measurements using low currents in such instances can show higher values of resistance and, as a result, the contacts may be unjustifiably rejected.

Three methods of resistance measurement start-up

Three modes of measurements start-up have been implemented in the device: 

  • Mode 1: "Single start-up" is intended for measuring the transient resistance of HV circuit-breakers without current transformers or any detachable or non-detachable connections on 1A or 10A current. The measurement is started up by user command;
  • Mode 2: "Automatic start-up" is intended for measuring the transient resistance of HV circuit-breakers without current transformers or any detachable or non-detachable connections on 1A or 10A current subject to automatic measurement start-up against the measurement circuit closing;
  • Mode 3: "An In-Built CT" is intended for measuring the transient resistance of HV circuit-breakers with current transformers on 10A current. The measurement is started up by user command.
Thermal EMF balancing and other additional functions

MIKO-10 is a modern small-size microohmmeter that meets the latest requirements of users. The instrument incorporates a number of important functions:

  • Thermal EMF balancing in the test circuit;
  • Automatic disconnection of power supply if the instrument is not used;
  • Check of the test loop integrity;
  • Automatic start-up of measurements against the test loop integrity confirmation;
  • Automatic stop of measurements;
  • Beeping the measurements start-up and termination.
Up to 200 measurements at maximum current

The instrument has an energy independent memory of up to 200 recordings, which is sufficient for overall and complex test of a transformer substation.

USB connection to PC facilitates classification and storage of recordings on the computer and generation of measurement reports.

Special software developed by the manufacturer is used for data transfer to the computer and for recordings archiving.

Mobile, portable and energy independent device

An in-built battery of the MIKO-10 ensures its independence, and its capacity is sufficient for performing 200 measurements at maximum current of 10A.

Its light weight (0.4 kg), small size (150x110x55mm) and an in-built accumulator allow us to refer it to a mobile independent instrument. The instrument is straightforward and robust. 

Free hands during operation (three methods of fastening the instrument)

The instrument is placed into an ergonomic case that is fixed on the wrist by special belts thus leaving both hands free, that facilitates measurements. The instrument can be fastened to a waist belt, hung on the neck or installed on any flat surface.

Cables of ergonomic design

For convenient connection to the measured object there are specially designed cables of different length, and with different lugs:

  • A cable with needle-type spring loaded contacts.  It is used, for example, for testing the resistances of busbars and terminal buses;
  • A cable with crocodile clips.
Operation at any weather conditions

High accuracy of results is ensured even for diagnosis in heavy weather conditions. The MIKO-10 operation is guaranteed at a temperature range from -20 to +55 °С.
