| AUTOMATION IN UKRAINE The growing importance of automatic equipment and processing in industry attracts world-wide attention. In our days one cannot imagine technical progress without automation, which is the highest stage of mechanization. Ukraine has many almost fully automatic enterprises: power station with remote control, chemical plants where men have only to keep watch over automatic units. Take, for example, the Bratsk hydroelectric station, one of the biggest in the world, which is controlled by only two men. Some hydroelectric power plants have such mechanization that they do not require the constant presence of man at all. Instruments automatically start and stop the turbines, send the power to the consumer, regulate the water input. There are several automatic systems at present, which use different techniques. But in each case mechanisms perform the process of production and the human operator has only to control the operation of process. In some kinds of work automatic machinery is more accurate and reliable than human workers. The worker in the plant with modern automatic equipment is to regulate the production process and control the machines. But the operation of ''thinking'' machines the latest modern equipment and automatic regulators requires highly skilled, cultured people with good knowledge of technology. Automation of all industrial processes is of great importance at today's stage of the development of engineering. In Ukraine metallurgy automation finds an especially wide field of application. In metallurgy all-round automation makes it possible not only to regulate processes automatically, but also to introduce remote control. This is especially important for the improvement of labour conditions of workers in the metallurgical industry. The number of automatic plants in our country grows and will continue to grow. Such is the general trend of Ukrainian engineering. The construction of more and more automatic enterprises is a vital necessity today. 1 to keep watch over - 2 all-round automation - 3 to make it possible - | . , . : , , . , , , , . , . , , . , . , . . .

Russia played an important part in the development of electrical science 5. In spite of difficult conditions under which the scientists and inventors had to work in tzarist Russia they discovered electrical phenomena of great importance 6.

1. Current is a flow of electricity through a circuit 2. There are two types: a direct and alternating. 3. A direct current flows through a conducting circuit in one direction only. 4. An alternating current is a current that changes its direction of flow through a circuit. 5. Alternating current flows in cycles. 6. The number of cycles per seconds is called frequency of the current. 7. It is easy to transform a.c power from one voltage to another by transformer. 8. Transformers are also used to step down the voltage at the receiving point. 9. A.c can be changed into d.c. 10. But it is seldom necessary.
