The main application direction Electrotechnical

"Electrical Technology" non-electric class professional basic compulsory, which includes two parts: circuit analysis and motor control, and relay contactor control system is an important component of the latter is the main application of electrical  electric transformer . Relay contactor control system by means of electrical control to achieve a certain  Voltage stabilizer , both in respect to the control electrical applications, but also related to how effectively its constitution circuit control requirements. For students, this is a new content, but also the course one of the difficulties in learning, often there are certain difficulties.
