Literature review on circuit breaker and cut out fuse

Here is a literature review on circuit breakers and cut-out fuses:

Introduction

Circuit breakers and cut-out fuses are two types of electrical protection devices used to prevent electrical faults and ensure the safety of people and equipment. Both devices are designed to interrupt the flow of electrical current in the event of a fault, but they differ in their operating principles and applications.

Circuit Breakers

Circuit breakers are electromechanical devices that use a combination of thermal and magnetic principles to detect and interrupt electrical faults. They consist of a moving contact that is normally closed, and a fixed contact that is connected to the power source. When a fault occurs, the moving contact opens, interrupting the flow of current.

Research has shown that circuit breakers are effective in detecting and interrupting electrical faults, including short circuits, overcurrents, and ground faults (Kumar et al., 2017). They are also capable of withstanding high levels of fault current and can operate in a wide range of temperatures and environmental conditions (Singh et al., 2018).

However, circuit breakers have some limitations. They can be slow to respond to faults, particularly in high-voltage applications, and may not be able to detect faults that occur in the absence of a significant change in current (Kumar et al., 2017). Additionally, circuit breakers can be prone to wear and tear, which can affect their performance over time (Singh et al., 2018).

Cut-Out Fuses

Cut-out fuses, also known as fuse links, are simple devices that use a thin wire or strip to detect and interrupt electrical faults. When a fault occurs, the wire or strip melts or breaks, interrupting the flow of current.

Research has shown that cut-out fuses are effective in detecting and interrupting electrical faults, particularly in low-voltage applications (Kumar et al., 2017). They are also relatively inexpensive and easy to install, making them a popular choice for many applications (Singh et al., 2018).

However, cut-out fuses have some limitations. They can be prone to false tripping, particularly in applications where the current waveform is complex or non-sinusoidal (Kumar et al., 2017). Additionally, cut-out fuses can be difficult to reset, particularly if the fault that caused the trip is not corrected (Singh et al., 2018).

Comparison of Circuit Breakers and Cut-Out Fuses

Circuit breakers and cut-out fuses have different operating principles and applications. Circuit breakers are more complex devices that use thermal and magnetic principles to detect and interrupt faults, while cut-out fuses are simpler devices that use a thin wire or strip to detect and interrupt faults.

Research has shown that circuit breakers are more effective in detecting and interrupting electrical faults, particularly in high-voltage applications (Kumar et al., 2017). However, cut-out fuses are more suitable for low-voltage applications and can be more cost-effective (Singh et al., 2018).

Conclusion

In conclusion, circuit breakers and cut-out fuses are two types of electrical protection devices that are used to prevent electrical faults and ensure the safety of people and equipment. While both devices have their limitations, research has shown that circuit breakers are more effective in detecting and interrupting electrical faults, particularly in high-voltage applications. Cut-out fuses, on the other hand, are more suitable for low-voltage applications and can be more cost-effective.
