Globalization Partners International Interview Questions and Answers

Q1. What is breaker ?
Ans. 
A breaker is an electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
• Breakers automatically stop the flow of electricity when a fault is detected.

• They come in different types such as circuit breakers, fuse boxes, and residual-current devices.

• Breakers can be reset manually after tripping to restore power.

• Common brands of breakers include Siemens, Schneider Electric,

Q4. How breaker works ?
Ans. 
A breaker is an electrical switch that automatically interrupts an electrical circuit during abnormal conditions.
• Breakers are designed to protect electrical circuits from overloads, short circuits, and other faults.

• When a fault occurs, the breaker trips and interrupts the flow of electricity to prevent damage to the circuit or equipment.

• There are different types of breakers such as thermal, magnetic, and hybrid breaker...read more

Q5. Why 66kv lines used ?
Ans. 
66kv lines are used for transmitting electricity over long distances with minimal power loss.
• 66kv lines are used for long distance transmission of electricity

• Higher voltage reduces power loss during transmission

• 66kv is a common voltage level for transmission lines

• Lower voltage lines would result in higher power losses

Q6. What is transformer ?
Ans. 
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of two or more coils of insulated wire wound around a core

• Primary coil receives electrical energy and induces a magnetic field in the core

• Secondary coil receives the magnetic field and converts it back into electrical energy

• Used to step up or step down voltage levels in power di

Q1. What is Lightning Arrester ?
Ans. 
A lightning arrester is a device used to protect electrical systems from the damaging effects of lightning strikes.
• It is also known as a surge arrester or lightning diverter.

• It is typically installed on power lines, communication lines, and electrical equipment.

• The arrester diverts the high voltage of a lightning strike to the ground, protecting the system from damage.

• It works by providing a low-resistance path for the...read more
