Star (Y) connection and triangle (delta) connected closely follows the load phase voltage, phase current and phase voltage, line current of three symmetric relations: star connection and triangle connection method Star connection: The I line =I, U line = 3 * U *, P phase, =U phase, * ...
Delta connection is the three coil end to end is shaped like a triangle, three connection points are respectively connected with the three-phase power supply. The voltage at each end of the coil is equal to the phase voltage from the voltage at both ends. The voltage at each end of a ...
2) Y/△ connection 星形/三角形连接 1. For the differential protection of power transformers with Y/△ connection, the currents on the Y-winding are usually revised on magnitudes and phase angles. 在星形/三角形连接组的变压器差动保护设计上,原有做法一般是对星形(Y)侧电流转角,进行二次电流的...

三角形接法与星形(Delta connection and star)Three - phase motor, star and triangle two kinds of connection method, is the design of fixed connection method, can not be changed. For example, the three-phase 380V star connection method is changed into triangle connection, and the adaptive ...
The first is that of a delta connected motor compared to a star connected motor of the same power and voltage ratings; the star connected motor in this case is then mathematically the delta connected motor's equivalent star connection. The second case considered is that of a delta connected ...
