Industrial microhmmeter MIKO-1 is designed to measure the transient electrical resistance to dire­ct current:

  • contacts of high-voltage and auto­matic circuit breakers;
  • contactors, breakers, connect­ors;
  • bolted, welded and soldered connections of conductors and buses;
  • rail bonds, wheels of cars, etc.

User participation in the measurement process is minimal. The me­asurement process is started by pressing one button, without any additional settings.

To obtain reliable values, it is recommended to make measurements at sufficiently high currents through the transient resistance, which is set out, for example, in IEC 56 standards (I≥50A).

Measurements are made using a hi­ghly stable DC current. This all­ows measuring the electrical resis­tance of circuits containing current transformers, which are usually fitted on high-voltage dead tank circuit breakers.

MIKO-1 is designed for operation in harsh electromagnetic e­nvironment of power stations and sub­stations, with measuring channels of the de­vice allowing to suppress electromagnetic interference of industrial frequency.

Integrated battery in MIKO-1 provides its portability and has a capacity sufficient to per­form to 100 measurements. It is charged from an internal charger powered by the mains.

The device has a small weight (3.6 kg) and small dimensions; a special bag provid­es its convenient movement, which allo­ws you to ascent with it on any circuit breaker.

If you have to carry out diagnostics in difficult weather conditions, you can be sure of the accuracy of the results. The MIKO-1 microohmmeter is guaranteed to operate at temperatures from -15 to + 40° C.

    "Uralelektrostroy", LLC

    "Uralelektrostroy", LLC has been using MIKO-1 microohmmeter since 2008. During this time, the device has established itself as a simple, unpretentious in use, but quite an accurate device. Our employees like the compactness of both device and test cables to be used. We also would like to note that the cable itself is elastic and can be used at low temperatures, and that is an significant factor when talking about the geography of our work. One more advantage is the convenience of the test cable with needle spring-loaded contacts that is convenient for resistance measurements of busbars.

    Only one small disadvantage has been identified: the inability to work from the network, but it is easily compensated by the fact that the battery is allowed to be changed on our own.

    Considering the above, we would like to recommend MIKO-1 microohmmeter to companies that are operating high-voltage equipment, as well as to laboratories that are working at energy facilities.
