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 in a substation.

Vacuum circuit breaker is one of the major critical components that controls and protects the power system. The breaking capability of the vacuum switch directly affects the safety of the power system. However, the breaking capability of the vacuum switch is determined by the morphological characteristics of the vacuum arc images. In this paper, in order to research the variation of the vacuum arc, a high-speed CMOS camera system is used to collect the vacuum arc images within a short gap (7mm), the morphological characteristics of the vacuum arc images are extracted based on the digital image processing. At last, the variation of the arc is analyzed.
