Fastening the measuring cable of the MIKO-8M(A) milli-ohmmeter to the diagnostic object

An example of fastening a measuring cable SKB041.18.00.000 of a milli-ohmmeter of MIKO-8M(A)

The MIKO-8M(A) milliometer is developed to measure DC resistance in the range from 1 µOhm ÷ 10 kOhm for the current of up to 10А for:

Windings of power and measurement transformers, windings of electric motors, generators, linear compensators and windings of other high-inductance equipment;
Contacts of circuit breakers, resistors, buses and other inductance-free circuits;
Equalizing, current limiting and other resistors of high-voltage circuit breakers;
Сables.

The device provides a fully automated process of measuring the resistance of a high inductive load and compensation of thermoelectric power in the external circuit.

MIKO-8M(A) implements specialized measurement modes for various configurations of 10 objects (resistive object, inductive, voltage transformer, current transformer and power transformer, generator, motor, compensator, connection filter and magnet), taking into account their specific features, while The user can select a typical object from the proposed list or create his own object.

The instrument automatically takes into account the configuration of the object for adjusting the measuring modes.

Depending on the object type, you can select special measurement modes. For example, for a resistive object:

AUTO: the measurement starts automatically by the circuit closed.
SINGLE: the measurement starts upon the User's comman (by pressing the START button).
PERIOD: the measurement starts automatically in prespecified time intervals.

For an inductive object, the User can also select one of two modes:

MANUAL: start and stop of the measurement are conducted manually by pressing the START button.
AUTO 1Ph: the measurement is initiated by pressing the START button and stopped automatically if criterium specified is reached.

AUTO 1Ph mode has SKB EP patented automatic measurement method that guarantees results with the highest accuracy.

It is achieved by setting the max current in the measurement circuit not on a staggered basis (depending on the value of the measured resistance), but continuously w/o fixed measurement ranges in a wide load range.

This measurement mode provides high signal level in a complex electromagnetic environment of industrial production or substation. Moreover, in AUTO modes of the measurement process the instrument produces the highest current that enables guaranteed saturation of the transformer magnetic system.

MIKO-8M(A) has a built-in archive of up to 200 measurements for viewing, copying or deleting data. And thanks to the possibility of choosing an object at the measurement stage, the results are presented more systematically. This facilitates interaction with the archive.

The group of MIKO-7M(A), MIKO-8M(A) and MIKO-9(A) instruments has a number of automatic calculation functions:

Auto δ calculation of Rphase between one another.
Auto conversion of Rlinear to Rphase. Linear windings are Delta or Star/Wye (with no neutral) connected.
Auto correction of R measured at t° to R at t°p.
Auto δ calculation between Rcorrected and Rp.
Auto calculation of t° by its R.

OLTC in-place check mode allows the User to assess the state of the switching OLTC equipment with current limiting resistors without removing contactor tank cover.

This mode involves measuring of instantaneous current drops. Test current firstly passes through the transformer winding and then through OLTC contacts at changing from one tap to another. The DRM graph is built on the basis of the measurement results and shows current change during tap changing. This graph enables to check tap changing time and general object state.

Analysis of the acquired graphs enables not only to sort out OLTC by fault-free/faulty criteria, but also to define the nature of the defect eliminating opening of fault-free OLTCs. Milliohmmeter mode and DRM test complement each other and provide the User comprehensive informa- tion about the transformer state.

MIKO-8М(A) has the safety certificate IEC 61010-1. The instrument also meets the requirements of electromagnetic compatibility that are applied to class A instruments according to IEC 61326-1.

The instrument has a high degree of protection against:

test cable or mains cable breakdown;
excess of measuring current;
emf of self-induction;
overheat of the test block.

At disconnection of the measuring cable from transformer bushings or from the instrument as well as at disconnection of the mains cable from the mains in the course of measurement, emf of self-induction of up to several kV is generated in the disconnected circuit and the electric arc appears in the break point.

MIKO-8М(A) is characterized by the redundant protection against emf of self-induction in case of involuntary disconnection of the measuring cable or power cable protecting users from electric shock and the instrument from being damaged.

MIKO-8M(A) is equipped with a color graphic touch screen display of high brightness and an intuitive interface, which facilitates interaction with the device.

Management can be carried out through the keyboard, touch screen or from a special mobile application that allows you to maintain and synchronize the enterprise measurement database from the instrument, and also makes it possible to control the device remotely.

None of the measuring cables is included in the standard equipment of the MIKO-8M(A) device.This allows the customer to choose exactly that kit.

To select the User and the convenience of connecting to the object, measuring cables of different lengths and different types of clamps/fasteners are specially designed:

Current cable 1 x 8.5 m with crocodile clips (jaw up to 80 mm);
Current cable 1 x 8.5 m with a G-clamp (jaw up to 103 mm) for connection to transformer;
Current cable 1 x 4 m with crocodile clips (jaw up to 25 mm) for resistance measurement of CT and VT windings;
Current cable 1 x 3 m. Weight 0.5 kg. With 2 crocodile clips (jaw up to 25 mm) and 2 removable probes (length: 70 mm, plug: 3 mm) for transient resistance measurement of CT and VT contact joints and windings.

Condensate Stabilization Plant named after V.S. Chernomyrdin (Surgut CSP) the branch of Gazprom Pererabotka, LLC

Our plant has been using MIKO-8 milliohmmeter since 2016. The device is built into a good strong case that is convenient for transportation. During the time of use, with the help of MIKO-8 were diagnosed more than 100 units of electrical equipment (transformers, electric motors of various capacities and other equipment). One of the main advantages for our staff was the ability of automatic recalculations of deviations with indication of parameters and their saving into the device memory. The second advantage is the possibility of further processing of measurement results on a PC using specialized software. Also, among the advantages we can highlight the measurement speed, intuitive operation of the device, and its small dimensions.

Among the disadvantages, we note the use of non-standard connectors on the test cables and the inability to use third-party cables, the lack of auto power selection of the device.

[Manufacturer note]: Cable connectors that are implemented in our devices actually involve the use of the cables only of our production. Thereby we guarantee the reliability of the devices that you use, and we are responsible for the results that you get during measurement process. Unfortunately, when using third-party cables, we cannot guarantee the correctness of the data obtained.
The possibility of auto power selection is implemented in the upgraded versions of our milliohmmeters, more information about their characteristics can be found via the link. In addition, in modern milliohmmeters, the power can be set both automatically and manually.

MIKO-8 copes well with the assigned tasks. We can recommend it to other companies.

MegionEnergoNeft, LLC

In May 2018, MegionEnergoNeft LLC received a pilot operation of the MIKO-8 device for measuring the direct current resistance of windings of oil and dry transformers from 0.4 to 110 kV of various types and designs. The device was operated both during the repair of electrical equipment during the repair of power transformers, and at transformer substations in the course of acceptance tests of electrical equipment serviced by MegionEnergoNeft LLC.

During exploitation, the advantages of the instrument were revealed, for example: small dimensions, a convenient housing for transportation and operation, an intuitive menu, a built-in measurement archive that allows you to speed up the measurement, simplify the processing of the results and automatically recalculate the data. Measurements are carried out in a short time, which in comparison with other devices significantly reduces the time of measurements. A positive feature of MIKO-8 is the ability to measure the resistance of the windings of power transformers with on-load tap-changers without disconnecting the device from the network and the equipment being measured, which significantly reduces the time it takes to take measurements.

Information is displayed on a large contrast screen that allows readings without voltage. During operation, no shortcomings were detected, the device works flawlessly.

As wishes for additional equipment, there is not enough portable compact battery pack with a built-in charger and a plug for connecting in the field [Manufacturer comment: The MIKO-8 millimeter is discontinued – in its place is a new modification of the MIKO-8M / MIKO-8M(A) (with built-in battery)].

According to the results of trial operation, it was found that this instrument meets the declared characteristics and significantly superior to instrument of a similar purpo

TESS Siberia, LLC
We have been using MIKO-8M(A) for two months. And the following positive advantages were revealed during the operation process:
1. Built-in rechargeable battery allows to make measurements without connecting the device to the network.
2. Checking the continuity of the measurement circuit of the object allows you to make sure that the device is connected correctly.
3. The presence of the multi-touch screen and buttons ensures reliable control of the device.
4. Extended resistance range up to 10 kΩ (comparing to MIKO-7) allows to measure resistance of the voltage transformer windings.
5. The presence of the archive ensures convenient processing of the numerous measurement results in various objects.
Revealed remarks:
1. The inscription "Measurement in progress, do not break the circuit" is too small, hardly noticeable in sunlight (it is worth increasing the font of all inscriptions).
2. It is necessary to increase the volume of the sound signal, because in conditions of heightened noise level it is not audible (in MIKO-7 the sound signal is much stronger).
3. For the convenience of typing on the keyboard, please add a virtual QWERTY keyboard.

Branch "Gusinoozyorskaya SDPP" JSC "Inter RAO – Electric Power Plants"
Our company has been using MIKO-8M ohmmeter since 2018.

The device is built into a good robust case that is convenient for transportation in the extreme conditions of Russian roads. Device is equipped with comfortable-to-use control via buttons and multi-touch screen. The key point when choosing a device was the upper board of resistance range, as we are faced with the measurements of voltage transformers, and the price. MIKO-8M seemed to be an ideal choice. One more advantage is that test cables are not included to the complete set of the device because we were able to choose the most suitable one and not to overpay for cables that we would not use in our work.

The device is doing well with the assigned tasks:
1. resistance measurements of voltage transformers 15-220 kV;
2. resistance measurements of generators and electric motors windings;
3. winding resistance measurements of power transformers 6-220kV.
We would like to recommend MIKO-8M(A) milliohmmeter to other companies that are involved in the energy industry.

Our company has been using MIKO-8M milliohmmeter since 2019.

The device is built into a good robust case. It is convenient in working process on production sites. Device is convenient to be operated via buttons or touch screen. An important point when choosing the device was that the measured transformer winding was quite quickly saturated and the EMF appeared was balanced. Previously we have been using Vitok ohmmeter, but it significantly inferiors in the above-mentioned parameters to the MIKO-8M milliohmmeter. Several more advantages are the upper range of the resistance measurement, as we have to deal with the measurements of voltage transformers, and the price. The correlation of all the requirements and possibilities turned out to be the most optimal with MIKO-8M. One more advantage of this device is that none of the measurement cables is included to the complete set of the device. We were able to choose the most suitable one for us and not to overpay for cables that we would not use in our work.

The device copes with the assigned tasks very well (DC resistance measurement of the windings of power, tapped, auxiliary, voltage transformers). We could definitely recommend it for other companies in the energy industry.

Kurskenergo the branch of Rosseti Centre, PJSC

2 measurement devices manufactured by SKB EP, LLC are used in the Western section of the diagnostics service of Kurskenergo the branch of Rosseti Centre, PJSC: PKR-2M transformer OLTC analyzer and MIKO-8M milliohmmeter. PKR-2M device has been used since 2018, and MIKO-8M device has been used since 2019.

These devices are used for diagnostics of power and measuring transformers of voltage 110, 35, 10 kV (MIKO-8M) and OLTCs of power transformers of 110, 35 kV (PKR-2M).

In practice, both devices have proven themselves from the best side: compact, robust case, convenient and easy-to-use interface, the ability to select the necessary schemes and groups of winding connection. The ability to create and maintain an archive, including the ability to enter factory test data that allows you to carry out the primary analysis of diagnostics results directly at the workplace. High-quality of test cables and clamps, the possibility of adjusting the scope of the complete set. All this greatly reduces the time and labor costs when carrying out equipment diagnostics in comparison with the previously used fleet of devices. It should also be noted that there is software for analyzing and storing diagnostics results on a PC. Furthermore, there is the ability to obtain the necessary information or consultation directly from the device developers.

The use of PKR-2M and MIKO-8M devices manufactured by SKB EP, LLC brought the diagnostics of power and measuring transformers to a new, higher quality level.

PKR-2M and MIKO-8M devices manufactured by SKB EP, LLC are recommended to be used by enterprises and companies engaged in the repair and diagnostics of power and measuring transformers.
