Krasnoyarsk Power and Mechanical Plant, LLC
MIKO-7M milli-ohmmeter has been operated at the Krasnoyarsk Power and Mechanical Plant since May, 2019.
The device has a clear software, a user-friendly interface, the device itself is easy to use in work.
The declared characteristics of the device are fully confirmed in practice.
The advantages of the device are its compact size, light weight and the ability to work from the network.
In addition, the device demonstrated good repeatability of the result, a wide range of resistance measurements, the possibility of manual adjustment of the test current.
We recommend this device for use in specialized enterprises.
The device was recommended to be purchased by the employees of electro technical laboratory of Tomskneftekhim, LLC.
Permenergo the branch of IDGC of Urals, OJSC
The technical maintenance and repair services of substations of the Permenergo the branch of IDGC of Urals, OJSC have been using PKV/M7, PKV/M6N, PKV/M5 and MIKO-1 devices manufactured by SKB EP, LLC for more than eight years.
The instrument pool consists of:
- ten PKV/M7 devices;
- nine PKV/M6N devices;
- two PKV/M devices;
- nine MIKO-1 devices.
With the use of the above-mentioned devices, the state diagnostics and adjustment of the following switching equipment are performed:
- oil circuit breakers VMP (E)-10, VMG-133, VKE-10, VMPP-10, VMG-10, VMB-10, VMP-10K, MGG-10, MG-10, VPMP-10, VK-10, VMK-35, VMP-35, S-35, VM-35, VT-35YU, VMUE-35, VMT-110, MKP-110, U-110;
- vacuum circuit breakers BB/TEL-10, VVE-10, VVE-10, VBE-10, VBE-10, VBE-10, 3AH5, VBE-10, VVE-M-10;
- SF6 circuit breakers VGBE-35, VGT-110, LTB-145;
- load break circuit breakers, isolators and short-circuiting equipment.
During the operation, PKV/M7, PKV/M6N, PKV/M5, and MIKO-1 devices have proven themselves on the good side. Due to the simple interface, they are simple and easy to operate, while they have high measurement accuracy, small overall dimensions and are very reliable.
PKV/M7 software makes it possible to create and maintain measurement archive, including the ability to enter nominal test data, which, in turn, allows you to conduct a primary analysis of the equipment diagnostic results directly at the workplace.
PKV-group devices allow you to measure a number of important parameters in one measurement cycle (time difference, pressure, speed, time, etc.), which significantly reduces the processing time and evaluation of the circuit breaker technical condition, and generally reduces the time for equipment repair.
The devices are equipped with a high-quality set of test cables, clamps, and fasteners.
We recommend the devices manufactured by SKB EP, LLC to other organizations working in the field of operation and adjustment of electrical equipment.
Krasnoyarsk CHPP-2 the branch of Yeniseyskaya TGC (TGC-13), JSC
Currently, Krasnoyarsk CHPP-2 the branch of Yeniseyskaya TGC (TGC-13), JSC has MIKO-2.3 and PKV/U3.1 devices in operation at the electrotechnical laboratory.
During the use since 2017, there have been no complaints or shortcomings in the operation of these devices. These devices are quite simple and easy to use.
We thank SKB EP, LLC for manufacturing high-quality devices, and hope for the appearance of new developments.
1. What device do you use (the number of devices used)? For how long?
Since June 2019, MIKO-9A device has been used in the amount of 1 piece.
2. What equipment do you check with the devices manufactured by SKB EP, LLC?
3-phase power transformers up to 1000 kVA and single-phase transformers of 6-10 kV. Also, high-voltage synchronous and asynchronous electric motors of 10 kV.
3. How convenient is it to use the device?
The device is very convenient for working with the tested equipment.
4. What functions of the device do you consider the best?
Measurements of the ohmic resistance of the windings of transformers and electric motors.
5. What problems or malfunctions were detected with the help of the device? On what kind of high-voltage equipment?
No malfunctions were detected. The device works flawlessly.
[Manufacturer note]: This question was not understood correctly by the specialists of KazTransOil, JSC.
6. Specify the economic effect you have received from using the device: the number of detected faulty objects from the entire list of diagnosed equipment, the number of man-hours saved when working with the device compared to using old measurement methods, etc.?
Working with this device speeds up the work on checking and testing the equipment. The measurement is performed faster, probably 5 (five) times, compared to analog devices.
7. Can you recommend our devices to other organizations?
I already recommend them to colleagues from other regions of Kazakhstan.
Prioksky EMPN the branch of FGC UES, PJSC
Currently, the following devices manufactured by SKB EP, LLC are used at the substations of the Prioksky EMPN:
With the help of these devices, all the necessary time and speed characteristics of high-voltage circuit breakers of various types are removed, as well as the transient resistances of the equipment contacts are measured.
All of the above-mentioned devices are easy to operate, have a compact design and light weight. These features allow them to be used directly at the installation site of the equipment that is being repaired.
During the operation, the devices have proven themselves to be good in terms of operation and measurement accuracy.
