Q2. Which types of Breakers
Ans. 
Types of breakers include circuit breakers, fuse breakers, and earth leakage circuit breakers.
• Circuit breakers are designed to protect electrical circuits from damage caused by overload or short circuit.

• Fuse breakers use a fuse to interrupt the circuit when an overload occurs.

• Earth leakage circuit breakers detect small stray voltages and disconnect the power to prevent electric shock.

• Other types include thermal-magneti...read more

Q1. How many arthing in electric
Ans. 
Earthing is an important safety measure in electrical systems.
• Earthing provides a path for fault current to flow safely to the ground.

• There are different types of earthing systems such as TN, TT, and IT.

• The number of earthing points depends on the type of system and the size of the installation.

• For example, a small domestic installation may have one earth rod, while a large industrial installation may have multiple ear...read more

Q2. What is the name of arthing 5 type
Ans. 
The five types of earthing are: plate earthing, pipe earthing, rod earthing, strip earthing, and water pipe earthing.
• Plate earthing involves burying a metal plate in the ground and connecting it to the electrical system.

• Pipe earthing uses a metal pipe driven into the ground and connected to the electrical system.

• Rod earthing utilizes a metal rod driven into the ground and connected to the electrical system.

• Strip earthi...read more

Q2. What is Pulse width in laser ?
Ans. 
Pulse width in laser refers to the duration of time that a laser beam is emitted.
• Pulse width is measured in seconds or milliseconds.

• It determines the amount of energy delivered by the laser beam.

• Shorter pulse widths are often used for precision cutting or welding.

• Longer pulse widths are used for applications like material processing or drilling.

Q3. What is BDV of Transformer oil?
Ans. 
BDV stands for Breakdown Voltage. It is a measure of the dielectric strength of transformer oil.
• BDV is the voltage at which the insulation between two conductors breaks down.

• It is an important parameter to determine the quality of transformer oil.

• BDV is usually measured in kilovolts (kV).

• Higher BDV indicates better quality and higher dielectric strength of the oil.
