https://www.ijert.org/review-on-circuit-breakers https://www.ijert.org/research/review-on-circuit-breakers-IJERTV9IS110133.pdf Any power system needs protection to protect it from any undesirable fault currents and that's why we have protection devices such as Circuit breakers which will break the current during faults to protect the system. This paper shows the basic classification of circuit breakers types and the basic knowledge for students to know this information.
Power Circuit Breaker Types Their Advantages and Disadvantage
Protection of power systems is as important as establishing of power systems. The protection system of any power systems must be fast and accurate to respond to abnormal condition and must eliminate the fault circuit from the system before any damage. For this purpose, we use different protecting devices, such as circuit breakers, fuses, relays etc. Circuit breaker is main protecting device in power system which works mechanically. It works in closed position during normal conditions and opens in abnormal condition. This paper discusses working of different types of circuit breakers, also discusses their working and medium used for arc extinction. This paper also discusses advantages and disadvantages of the circuit breakers.
Types of Circuit Breaker and its Application in Substation Protection
Indonesian Journal of Electrical Engineering and Computer Science
Power system consists of the generation, transmission, distribution, and substation. All the power system component requires suitable protection devices as the protection system to protect the system during fault occur. In this paper, the circuit breaker has been selected as one of the protection devices in several applications. The types of circuit breaker that has been reviewed in this paper are oil circuit breaker (OCB), air circuit breaker (ACB), sulphur hexafluoride (SF6) circuit breaker, vacuum circuit breaker, and DC breaker which are hybrid DC breaker and solid-state DC breaker. Normally, the systems or the circuits disrupted or damaged by the fault. To implement the protection system in the system or circuit, the type of faults and cause of faults should be known to overcome the fault. To provide the suitable voltage for the consumer, the substation is needed to control the voltage transmitted at high voltage from the generating station. Protection system is also required i...
Operation of Circuit Breakers: Data and Analysis
Multidisciplinary Journal for Education, Social and Technological Sciences
An attempt has been made for the analysis on Circuit breakers (CBs) this paper. First, the types and arcing phenomenon of Oil and SF6 Circuit breakers were briefly discussed. However, various CBs were analyzed in terms of certain outage frequencies and reliability indices to ascertain the most reliable CB. This was possible using data collected from the 33kV Transmission Company of Nigeria (TCN) New Haven, Enugu. After the analysis, Emene Industrial CB had the highest value of availability of 0.9999 and the lowest tripping report while Ezillo had the highest failure rate of 0.1032.
A Review Paper on Hybrid Circuit Breaker
IAEME PUBLICATION, 2015
To ensure safe and healthy operation of electrical power system network, high voltage circuit breakers are really important so that faulty sections can be effectively isolated from the healthy part of network. Depending on transmission line’s power rating vacuum circuit breakers and SF6 circuit breakers are an effective choice. A need of hybrid model of circuit breakers is analyzed by reviewing the merits and demerits of the two mentioned above.
Electrical Arching and Thermal Circuit Breakers: A Review
The essence of electrical protective devices is to mitigate damage, to maintain system stability, and to maintain electrical consuming devices at the rated operating limits. The hazards involve in the consumption of electrical energy for homes and any other place must be well understood; because this would signal warning for proper safety. Age long protective device known to almost 99% users' of electricity is circuit breaker. But this device has its limitations. A review is therefore presented to examine the duties and limitation of residential electrical circuit breakers based on available information.

This research work aims to simulate the effect on circuit breaker due to various types of faults occurred in distribution network. The various faults like single line to ground fault (L-G), double line to ground fault (2L-G), triple line to ground fault (3L-G) and line to line fault (L-L) are simulated and their effect on circuit breaker is also studied. Such type of fault causes failure to open and close, failure to operate as required etc., the various reasons behind these failures are increased contact resistance, damaged mechanical parts, decreased insulation. In this paper, an artificial neural network (ANN)-based technique is applied to indicate the severe damage and to monitor the failure modes in advance.

Transients Caused by Uncontrolled and Controlled Switching of Circuit Breakers
This paper describes transients caused by uncontrolled and controlled switching of high-voltage circuit breakers. Inrush currents due to shunt reactor energization were analyzed. Switching-off, energization and auto-reclosure of unloaded 400 kV transmission line is presented. Transient recovery voltage and voltage distribution between breaking chambers of circuit breaker are investigated. Calculation models were developed in EMTP-RV software and some field measurements are presented. Results show that controlled switching significantly reduces inrush currents and suppresses switching overvoltages.
