【正文】 nnection between the coils is the mon magnectic flux presen within the core. One of the transformer windings is connected to a source of ac electric power,and the second(and perhaps third) transformer winding supplies electric power to loads. the transformer winding connected to the power souce is called the primary winding or input the winding connected to the loads is called the secondary winding or input there is a third winding on the transformer,it is called the tertiary winding. Power transformer are constructed on one of two types of type of construction consists of a simple rectangular laminated piece of steel with the transformer windings wrapped around two sides of the type of construction is know as coreform .The other type consists of threelegged laminated core with the windings wrapped around the center leg .This type of construction is know as shell either case,the core is constructed of thin laminations electrically isolated form each other in order in order to reduce eddy currents to a minimum. The primary and secondary windings in a physical transformer are wrapped one on top of the other with the lowvoltage winding an arrangement severs two purposes: simplifies the problem of insulating the high voltage winding from the results in much less leakage flux than would be the two windings were separated by a distance on the core
