A Review on ARC Flash Analysis and Calculation Methods

Abstract

Analysis of an Arc detection system consider the standards, responsibility, sensitivity, security of overall system protection methods. This arc flash detection system coordinate different sections like as relay section, circuit breaker section, switchgear components withstanding capability at fault level, load section, neutral grounding section. The fast Arc detection and trip times are evaluated by Present state of optical fault detection sensors are implemented for fast identification and tripping of arc functions. Optical fault detection Sensors have some disadvantages are compare to conventional and other types. This sensors not only detect the Arc lighting sometimes it will detect lightning flash or welding. Conventional types are taking more time for tripping compared to sensor types. The combinational study needed for each type of arc detection schemes to avoid the nuisance tripping because it will affect the overall stability of the system. Different fault levels before and after arc ignition system need to maintain reliability of the system safely and securely.
