Triangle multidrop parallel connection three-phase motor winding short circuit detection circuit
For the triangle multidrop parallel connection three-phase motor, you need to separates the adapter connector of the winding. As the figure shows, you can connect the winding into the triangle, and connect one port with the secondary stage of the welding transformer T, another port of T is connected with an ammeter. After the power is connected, you need to connect the hand (which is connected with the ammeter) with the other two ends of the winding respectively to compare the current, the phase which has the smaller current value is the short circuit winding.
