10+ Star Delta Starter Power Circuit Diagram. We use it to reduce the starting current of the motor without using any external device or apparatus. So our main target is, at the starting time the motor windings should be connected in star and then it should be connected in delta.
After the appropriate time delay, the power is disconnected, windings reconfigured to delta and the power reconnected. Initially the motor is connected to star connection. The main circuit breaker c.b q1 serves as the main power supply switch that supplies electricity to the power circuit.
After the appropriate time delay, the power is disconnected, windings reconfigured to delta and the power reconnected.
10+ Star Delta Starter Power Circuit Diagram. Unlike manual star delta starter in automatic star delta starter as shown in figure 2.2 an external circuit namely. It shows the components of the circuit because simplified shapes, and the power and signal connections in between those devices. The main circuit breaker c.b q1 serves as the main power supply switch that supplies electricity to the power circuit. If the above winding is connected as star , the voltage per phase a star delta starter reduces the starting current by connecting the motor winding in star at the time of starting.
