New edition of the General Transformer Maintenance Guide. Current technical, economic and environmental challenges
The article presents the most important changes in the General Transformer Maintenance Guide, that have been introduced to ed. 2022. The reasons for the revision caused by changes in normative acts and regulations, the use of modern construction materials, the introduction of new measurement methods and the need to adjust the requirements to the changing population of transformers as well as economic and environmental factors are also discussed.
Keywords: transformer, maintenance guide, revision, tests and measurements, insulating oil, laboratory analyses

Measurement of dust electrification-capability in the installation
The article presents tests whose aim is to determine the static electricity hazard during current flow and dust ripping against the pipe made of plastic material. The pipe has been made of polycarbonate, an electrifying material. Dust has been inserted into the pipe. The dust movement was driven with pump. Electrostatic voltage on metal electrodes in several spots of the pipe and dust-feeding installation. Additionally, the electrostatic charge aggregated on the installation during electrification, has been transferred to the condenser.
Keywords: electrification, dust, electrostatics

Modern martensitic steels for energetics
The article is based on own research and available literature sources. It presents the characteristics of modern martenstick steels containing
11-12% Cr, i.e. Thor 115 and Super VM12. The chemical composition, heat treatment, microstructure, and functional properties of the analysed alloys have been characterized.
Keywords: martenstick steels, Thor 115, Super VM12, properties

New safety issues regarding electrical engineering
The article emphasizes new potential risks which might jeopardize workers who specialize in exploitation of new electrical energy sources, i.e. electric car drives, photovoltaics, and wind turbines. Various utilisation activities and occupational risks occurring during the utilisation of the above-mentioned machines have been discussed. The necessity of new OSH standards regarding the above-mentioned works has been mentioned.
Keywords: exploitation of new electrical energy sources, electric car drives, photovoltaics, wind turbines, new risks

The origins of the electrical machines industry in Poland up to 1939 and the foundation of factory in Żychlin
The article presents an outline of the beginnings and development of the electrical machines industry in the partitioned territories of the former Polish-Lithuanian Commonwealth (until 1918) and the Second Republic of Poland (until 1939). An attempt was made to characterise the most important plants producing electrical machines, both direct and alternating current, as well as transformers. Particular emphasis was placed on the factory in Żychlin, established in 1921, which already in the interwar period became one of the largest in Poland.
Keywords: industry, electrical machines, Żychlin, history of electrotechnology
