The calibration laboratory is registered in the Russian VNIIMS FSUE calibration system for technical competence in terms of performing calibration work.
All devices must be registered for warranty service, so you need to fill out the registration form. Each device received for repair undergoes initial diagnostics in order to determine the need for repairs. After repair, all devices are tested in a calibration laboratory with the issuance of a calibration certificate.
There are many different devices on the market that differ in operating principle, metrological characteristics, degree of automation, weight and size indicators and, of course, price, so that you do not get confused, we are always ready to advise you on all matters of choosing the right equipment and configuration.
Every year, more and more types of drives appear on the market, both high-voltage circuit breakers and on-load tap-changer transformers.
As part of the adaptation program of our devices to new high-voltage equipment, we do not stop working on the development of special fasteners for the possibility of the correct installation of measuring elements of devices.
Our devices are needed in many areas. These are various structures and units of energy, helicopter and aircraft construction, oil and gas processing industries, railways and much more.
Covering all these areas, it is necessary to create conditions for an understandable and convenient work with our devices, so that each user can easily carry out the most accurate diagnostics of an object.
Some specialists may have difficulty deciphering graphic data that contains important information about the state of the investigated high-voltage switch or transformer. You can purchase a subscription to the “chart analysis” service, or apply for individual training on working with SKB EP devices.
SKB EP instruments are successfully used in power systems, at hydroelectric power stations, PSPPs, state district power stations, thermal power plants and nuclear power plants, at industrial, oil and gas processing enterprises, in aircraft and helicopter engineering plants and on railways in the following countries:
- CIS countries (Armenia, Belarus, Kazakhstan, the Kyrgyz Republic, Moldova, Tajikistan, Uzbekistan, Ukraine);
- European Union countries (Bulgaria, Latvia, Lithuania);
- Asian countries (Cambodia, China, Indonesia, the Philippines, Thailand, Vietnam);
- South American countries (Ecuador, Peru);
- Oceania countries (Australia, New Zealand);
- African countries (Congo).
A group of researchers conducting investigation at the Institute of Energy Systems L.A. Melentyev SB RAS department, separated into a structural unit (design bureau VKK-7 consisting of 4 people) to be able to engage in their work and the development of devices for power engineers.
The SKB EP work began with the development of a “System for the thermal control of hydraulic units”. At that time, management faced a choice between several areas of enterprise development.
The earliest work result in the field of control of high-voltage equipment was the PKKHV-01 instrument. Prior to this device, most companies recorded data using a ruler, pencil, and paper, which badly affected the results. Therefore, the PKKHV-01 was a breakthrough in the diagnosis of high-voltage equipment.
Product development and realization of PKV/M1 - the first oil circuit breaker monitoring instrument.
Product development and realization of PKV/V1-18 (PKV/V1) and PKV/VB2-15 (PKV/VB2) air circuit breakers analyzers.
The first test models of instruments that were discontinued quickly enough to launch an improved model PKV/V3.
Product development and sale of PKV/V3 air high-voltage circuit breakers test analyzer.
This instrument has been on the market for 4 years and became the basis for the PKV/V3A instrument.
Product development and sale of the PKV/M4 the third oil high-voltage circuit breakers test analyzer model, which was in sale until the end of 2000.
A lot of instruments were made to implement this improved device model for monitoring air circuit breakers. Novelty allowed to launch release toon the market the PKV/V3A worthy instrument, which was in implementin the sale until 2005.
This year the official Service Center was established to provide after-sales services for the SKB EP products, as well as the Calibration Laboratory, which carried out all the work in cooperation with the East Siberian Branch of FSUE VNIIFTRI in the first instancein the first few days.
The same year was the start of the production and sale of two new models of PKV/M5N and PKV/M5A instruments, they caused a real “boom” in the instrumentation market and for 7 more years (until 2007) were popular among Users.
In the overhaul tests of most circuit breakers, in addition to monitoring the basic parameters of time, travelstroke and speed, one of the important points is to check the status of the circuit breaker contacts. Therefore, in order to cover a set of diagnostic work at the beginning of the 21th century the development of the first SKB EP micro ohmmeter - MIKO-1 began.
This instrument is one of the long-lived of our company in terms of implementation, because to this day it is one of the most popular micro ohmmeters in the Russian market and CIS countries.
The instrumentdevice fully meets all requirements of the Users and keeping with the asserted. It is easy to use, has the measurement range 1 μΩ ÷ 0.02 Ω and current up to 50A.
The updating time for the fleet of high-voltage circuit breakers began. Which means that production types became more and more, and it was no longer enough for Uusers to work only with specialized devices for monitoring air and/or oil circuit breakers. Therefore, research and development from the middle of 2002 began to produce a universal instrumentdevice for different types of high voltage circuit breakers control.
The first modifications of universal instrumentsdevices were PKV/U1 and PKV/U2, which entered the market in 2003.
The fourth model (modification) of PKV/M6N instrument for monitoring oil circuit breakers appeared. It, which is still relevant and is being sold on the Russian Federation and the CIS countries markets. During its implementation the instrument received a lot of positive reviews from many companies.
In parallel with PKV/M6N, the PUV-10 remote control for high-voltage DC and AC circuit breaker drives entered the market, which became additional recommended equipment for this instrumentdevice for setting complex operations and simple cycles.
This year the company began to develop a universal instrument for measuring electrical resistance in various types of electrical equipment. Work began on the MIKO-2 instrument, which was the first step toward creating the MIKO-2.2 and MIKO-2.3 devices.
After the development and production of PUV-10 with a current of 10A, almost immediately, work begins on the R&D of another external switching instrument PUV-50 with a current of 50A for testing circuit breakers with a DC drive.
After the first attempts to create universal instruments for monitoring circuit breakers (PKV/U1 and PKV/U2 in 2002), the company's developers did not stop at modernization and began work on the development of PKV/U3.1 and PKV/U3.0 instruments (phase 1 control) .
In the same year work began on the first instrument for monitoring circuit breakers in an ergonomic case - PKV/M7.
