Procedure of the lesson:


Text : Substations
А substation is designed to receive energy from а power system, convert it and distribute it to the feeders. Thus а substation serves as а distribution centre. Substations feed (supply) various consumers provided that their basic load characteristics are similar. Therefore the energy is distributed without transformation of the voltage supplied. Соmmоn substations comprise isolators, switchgear buses, оil circuit breakers, fuses, power and instrument transformers and reactors. Substations are classed into step up and step down ones. The step up substation includes transformers that increase the voltage. Connected to the bus bars of the substation are the power transmission lines of power plants of the system. As to step down substations, they reduce the voltage to 10 or 6 kV. At this voltage the power is supplied to the distribution centers and to the transformer substations of power consumers. А transformer substation serves for transmitting and distributing electric power. It
comprises
а storage battery, control devices and auxiliary structures. Transformer substations are classed into indoor and outdoor; both types are used for feeding industrial enterprises. Compared to other types of substations, transformer substations have certain advantages. Тhеу have flexible construction and easy and reliable operation. In case of а fault in the left hand section, the main circuit breaker opens while the normally ореn section circuit breaker closes and puts the voltage of the section to normal. Power from а substation is delivered to distribution centres.
Vocabulary:

auxiliary- вспомогательный, добавочный

breaker- выключатель, прерыватель

bus bar- собирательная шина

feeder- фидер

flexible- гибкий

to comprise- включать в себя

to distribute- распределять

as ... to- что касается

as well as- так же, как и

4. What components does
а substation comprise?

5. What types are substations classed into?

6. What are advantages of а transformer substation?
Task 5. Dialogues:

Training

  1. What do you do?

  2. I’m an apprentice with a local engineering firm. My training lasts for two years. Two days a week I study Engineering at a local college. If I pass all my exams,
