Directory Of Energy

Directory of energy consists of many sections of the power supply. In the electrical section, you will learn electrical safety rules electrical installations free of Pte and PTB for electrical equipment with voltage up to and above 1 kV pteep (circuit breakers, transformers, capacitors, cables) and пуэ7 equipment PUE electrical installations for lighting. In the thermal section, the power and mechanical equipment potau: here the information on energy fuels, industrial boiler units, the mpotom steam and hot water boilers, positive displacement machines (pumps, fans, compressors), heat exchangers. Includes a Chapter on Autonomous sources of energy supply enterprises.
