Transformers and wiring in the Main part of the main part of the content is the foundation, introduces the main connection in the form of an overview of the characteristics of different connection methods, their advantages and disadvantages and the principle of the transformer principle, according to mandate of the book chose to meet the design requirements The main task of wiring options. Shortcircuit current is a very important part, which introduces the purpose of calculating shortcircuit, principles, methods and specific data information for the design needs of the choice of high voltage electrical equipment, setting, checking and so to prepare. Selection and verification of electrical equipment is mainly employed symmetrical shortcircuit calculations for highvoltage electrical equipment (circuit breaker, disconnecting switch) validation. And protection of power configuration options, setting and calibration principles and methods.
