SIMPLEX ENGINEERING & FOUNDRY WORKS Electrical Maintenance Engineer Interview Questions and Answers

A motor is a device that converts electrical energy into mechanical energy to perform work.

• Motors are commonly used in various applications such as electric vehicles, industrial machinery, and household appliances.

• They come in different types such as AC motors, DC motors, and stepper motors.

• Motor capacity refers to its power rating, typically measured in horsepower (HP) or kilowatts (kW).

• Higher capacity motors can gene...read more

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It is named after Georg Simon Ohm, a German physicist who first formulated this law.

• This law is applicable to all types of circuits, including DC and AC circuits.

• It is use...read more

CT stands for Current Transformer and PT stands for Potential Transformer. They are used in electrical systems for measurement and protection purposes.

• CT is used to measure current in high voltage circuits by stepping down the current to a safe level for measurement.

• PT is used to measure voltage in high voltage circuits by stepping down the voltage to a safe level for measurement.

• Both CT and PT are essential components...read more

DTC structure stands for Direct Torque Control structure, a control method used in AC motor drives for precise torque and speed control.

• DTC structure is a control technique used in AC motor drives to directly control torque and flux without the need for a separate speed controller.

• It is based on the principle of controlling the torque and flux by selecting the appropriate voltage vectors in the motor.

• DTC structure offe...read more
