Q3. Substation overview
Ans. 
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

Q1. What is 1 angle and 2 angle in design
Ans. 
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

Q2. What is geometry and tolerance in design
Ans. 
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

Q2. Parts of transformer and function of each
Ans. 
Transformer parts include core, windings, and insulation. Core provides magnetic path, windings carry current, insulation prevents short circuits.
• Core: Provides magnetic path for flux to flow through

• Windings: Carry current and induce voltage

• Insulation: Prevents short circuits between windings and core

• Examples: E-core, C-core, shell-type transformer

Q3. Types of MCB in electrical system
Ans. 
Miniature Circuit Breakers (MCBs) are types of circuit breakers used in electrical systems to protect against overcurrent and short circuits.
• MCBs are classified based on their breaking capacity, rated current, and number of poles.

• Common types of MCBs include Type B (standard), Type C (medium delay), and Type D (high delay).

• MCBs can also be classified based on their tripping curve, such as Type K (fast tripping) and Typ
