Sterling & Wilson Electrical Project Engineer Interview Questions and Answers for Freshers

Q1. How to charge the Transformer?
Ans. 
A transformer can be charged by applying a voltage to its primary winding.
• To charge a transformer, connect a power source to its primary winding

• The voltage applied to the primary winding creates a magnetic field

• This magnetic field induces a voltage in the secondary winding

• The transformer is charged and ready to transfer power

Q2. Parts of transformer
Ans. 
Parts of a transformer include the core, windings, and insulation.
• Core: Provides a path for magnetic flux and is usually made of laminated iron or steel.

• Windings: Consist of primary and secondary coils, which are wound around the core.

• Insulation: Prevents electrical leakage and is used to separate the windings and core.

• Tap changer: Allows for voltage regulation by changing the number of turns in the winding.

Q2. What are the fundamentals of the power triangle?
Ans. 
The power triangle represents the relationship between real power, reactive power, and apparent power in an AC circuit.
• The power triangle is a visual representation of the relationship between real power (P), reactive power (Q), and apparent power (S) in an AC circuit.

• Real power (P) is the actual power consumed by the circuit and is measured in watts (W).

• Reactive power (Q) is the power that flows back and forth between...read more
