- Q1. What is the process of power distribution?
- Ans.
Power distribution is the process of delivering electricity from power plants to consumers through a network of transmission and distribution lines.
Electricity is generated at power plants using various sources such as coal, natural gas, nuclear, or renewable energy.
The electricity is then transmitted at high voltages over long distances through transmission lines to substations.
At substations, the voltage is reduced a...
- Q2. What are the different types of sources of electricity?
- Ans.
Different types of sources of electricity include fossil fuels, nuclear power, renewable energy sources, and batteries.
Fossil fuels (coal, oil, natural gas)
Nuclear power
Renewable energy sources (solar, wind, hydro, geothermal)
Batteries (lithium-ion, lead-acid)
Interview Questionnaire
4 Questions
- Q1. 1. Induction motor starting principle
- Ans.
The induction motor starting principle is based on the creation of a rotating magnetic field.
An induction motor starts by applying a voltage to the stator windings, creating a rotating magnetic field.
The rotating magnetic field induces currents in the rotor windings, which in turn creates a magnetic field.
The interaction between the stator and rotor magnetic fields causes the rotor to start rotating.
Different methods l...
- Q2. 2. Describe about transformer parts.
- Ans.
Transformer parts include core, windings, insulation, and cooling system.
The core is made of laminated iron or steel and provides a path for magnetic flux.
Windings consist of primary and secondary coils, which are insulated copper wires.
Insulation materials like paper, varnish, or oil are used to insulate the windings.
Cooling systems such as fans, radiators, or oil pumps are used to dissipate heat.
Other parts include b
- Q3. 3. How over current protection, differential protection and earth fault protection work.
- Ans.
Over current protection, differential protection, and earth fault protection are methods used to safeguard electrical systems.
Over current protection is used to detect and interrupt excessive current flow in a circuit.
Differential protection compares the current entering and leaving a component to detect faults.
Earth fault protection detects current leakage to the earth and isolates the faulty circuit.
Over current prot...
- Q4. 4. Cable construction and its layer.
- Ans.
Cable construction involves multiple layers for insulation and protection.
Cables are typically constructed with multiple layers for insulation and protection.
The innermost layer is the conductor, usually made of copper or aluminum.
The next layer is the insulation, which can be made of materials like PVC, polyethylene, or rubber.
Additional layers may include shielding to protect against electromagnetic interference.

- Q1. What is Ohm's Law?
- Ans.
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.
It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.
For example, if a circuit has ...
- Q2. What are Transformer protection?
- Ans.
Transformer protection refers to the measures taken to ensure the safe operation of transformers and prevent damage.
Overcurrent protection: Protects against excessive current flow.
Overvoltage protection: Safeguards against high voltage levels.
Overtemperature protection: Prevents overheating of the transformer.
Differential protection: Detects internal faults by comparing input and output currents.
Buchholz relay: Detects...

- Q4. What is motor protection?
- Ans.
Motor protection is a system designed to prevent damage to motors from electrical faults or overloads.
Motor protection devices include overload relays, thermal protectors, and circuit breakers.
These devices monitor the current and temperature of the motor to prevent overheating and damage.
Motor protection also involves proper grounding, insulation, and regular maintenance to ensure safe operation.
Examples of motor prot...
