The stator windings of the three-phase electromotor which is more than 10KW always use the varnished wire parallel winding and the Multidrop parallel connection. In one phase winding, if one or more wires cut off, you are difficult to judge by using the light, you can use the three-phase current balance method. The circuit is as shown in the figure, it uses the single-phase AC arc welding machine transformer T as the power supply, the three ammeters A1, A2 and A3 are connected with the U1, V1 and W1 respectively. After the power is connected, you can observe the current values of the three ammeters. In normal condition, the values are different.
