The oldest meter in the collection of the Energosbyt branch is 100 years old.

On the basis of the workshop for maintenance and repair of electric energy metering devices of the Energosbyt branch of RUE “Vitebskenergo”, enthusiasts, primarily the foreman of the workshop, G. Martinovich, collected a collection of electric energy metering devices. Here are various examples of induction meters, produced in different countries in different countries of Eurasia. Some of the meters were operated on the territory of Belarus and entered the museum from the exchange fund. Some copies were kept by the population, were in attics, in cellars and garages. Gradually, the news about the collection of the Energosbyt branch spread among people, the word of mouth effect worked. And the inhabitants of the region began to bring their rarities to the power engineers themselves. Counters in the collection came from all the production and sales sites of the branch located in the Vitebsk region.

Now the collection contains counters produced in various years in Germany, the USSR, Poland, Switzerland, Czechoslovakia, Hungary, Romania, Bulgaria, China, Japan and other countries. The oldest device in the collection is the WZ3, which was released in Germany in 1919 immediately after the end of World War I. In the current 2019, he turned one hundred years old. The maximum current for which this meter was designed was 3 A (a little more than half a kilowatt), then this was considered quite sufficient. The developed International System of Units at that time did not yet find wide application, therefore such units as Ampere, Volt, Hertz were written on the device either in completely Latin letters, or depicted graphically. In the course of implementing the GOELRO plan, from the mid-1920s the production of electric meters in the Soviet Union was established.

The exhibits are interesting to track the phased development of engineering. Gradually, in addition to accounting for electric energy, meters began to perform other functions. At the most critical facilities, it became necessary not only to record the final readings of the consumed electricity, but also to know its hourly and daily consumption. This idea was first implemented in Germany in the late 30s of the 20th century with the creation of a three-phase induction meter FM4eEGSY15, combining the functions of a counter and a recorder. After the Second World War, a number of countries developed metering devices that allow the use of different tariffs for different times of the day. The functions of 2 and 3 tariffs were implemented. An interesting single-phase induction meter manufactured in Smolensk in 1958, in which the idea of ​​prepayment was realized. The device combined the functions of a counter and a payphone. Coins that got into the coin acceptor turned out to be in a transparent case, which was attached below to the device body and was easily accessible. For certain reasons, this electric meter is not widely used.

The counters produced after the collapse of the USSR in independent Belarus and the CIS countries are also represented in the collection.

The exposition is located at the entrance to the workshop for maintenance and repair of electric energy metering devices of the Energosbyt branch and meets every employee and visitor. The collection of electricity metering devices is actively used in training personnel of the Energosbyt branch and in mastering their specialty. Touching the history of technology, visual confirmation of the development of the instrument park, engineering makes this training more lively and interesting, fills the dry abstract information with real objects that can be considered, and if desired, touched.
