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.
Thecombinational 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.
