Q4. What are the types of transformer losses
Ans. 
Types of transformer losses include copper losses, iron losses, and stray losses.
• Copper losses: Also known as I^2R losses, occur in the copper windings of the transformer due to resistance.

• Iron losses: Also known as core losses, occur in the transformer core due to hysteresis and eddy currents.

• Stray losses: Occur due to leakage flux and imperfect magnetic coupling between the windings.

• Examples: An example of copper los...read more

Q5. Working principle of generator
Ans. 
A generator works on the principle of electromagnetic induction to convert mechanical energy into electrical energy.
• Generators use a magnetic field and a conductor to create a flow of electrons, generating electricity.

• When the conductor moves through the magnetic field, it induces a current in the conductor.

• This current is then collected and transferred through wires to power electrical devices.

• Examples of generators i...read more

Q1. Difference between IDMT relay and transformer differential relay
Ans. 
IDMT relay is used for overcurrent protection while transformer differential relay is used for differential protection.
• IDMT relay operates based on inverse time-current characteristic curve

• Transformer differential relay compares the currents entering and leaving the transformer windings

• IDMT relay is used for protecting electrical equipment from overcurrents

• Transformer differential relay is used for detecting internal f

Q2. How solar energy in solar panels work
Ans. 
Solar panels convert sunlight into electricity through photovoltaic cells.
• Solar panels contain photovoltaic cells that convert sunlight into electricity

• When sunlight hits the cells, it excites electrons, creating a flow of electricity

• The electricity generated can be used to power homes, businesses, or stored in batteries for later use
