Sterlite Technologies Maintenance Engineer Interview Questions and Answers

Star delta starter is a type of motor starter used to reduce the starting current of an induction motor.

• It consists of three contactors and a timer.

• During starting, the motor is connected in star configuration to reduce the voltage across each winding.

• After a specified time, the motor is switched to delta configuration for normal operation.

• This reduces the starting current and torque, preventing excessive heating and m...read more

KCL and KVL are fundamental laws in electrical engineering.

• KCL (Kirchhoff's Current Law) states that the sum of currents entering a node is equal to the sum of currents leaving the node.

• KVL (Kirchhoff's Voltage Law) states that the sum of voltages around any closed loop in a circuit is equal to zero.

• KCL and KVL are used to analyze and solve electrical circuits.

• KCL and KVL are based on the principle of conservation of c
