Lucy Electric Design Engineer Interview Questions and Answers

1 angle and 2 angle are terms used in engineering design to describe the orientation of a part or feature relative to a reference surface.

• 1 angle refers to a feature that is oriented parallel to the primary datum plane

• 2 angle refers to a feature that is oriented perpendicular to the primary datum plane

• These terms are commonly used in geometric dimensioning and tolerancing (GD&T) to specify the orientation of features o...read more

Geometry and tolerance in design refer to the dimensions and allowable variations in a part or product.

• Geometry refers to the shape and size of a part or product.

• Tolerance is the allowable variation in dimensions to ensure proper fit and function.

• Tolerances are specified using symbols like +, -, or a range of values.

• For example, a hole may have a diameter of 10mm with a tolerance of +/- 0.1mm.

• Tolerances can affect the

1 angle and 2 angle are terms used in engineering to describe the orientation of a part or feature in relation to a reference plane.

• 1 angle refers to the orientation of a part or feature with respect to one reference plane

• 2 angle refers to the orientation of a part or feature with respect to two reference planes

• These terms are commonly used in engineering drawings to specify the orientation of features for manufacturin

A substation is a facility used for transforming voltage levels in an electrical power system.

• Substations receive high voltage electricity from power plants or transmission lines

• They transform the voltage to a lower level for distribution to homes and businesses

• Substations may also include equipment for protection, control, and monitoring of the power system

Transformers are classified based on their construction and cooling methods, such as dry-type, oil-filled, and cast resin transformers.

• Transformers can be classified as dry-type, oil-filled, or cast resin based on their construction and cooling methods.

• Dry-type transformers use air as the cooling medium and are suitable for indoor applications.

• Oil-filled transformers use oil as the cooling medium and are commonly used ...read more
