  • As usage of electric power is increased, the electric fire accident occurrences are growing, too. According to statistics it can be known that electric fire occupies the most weight. However, the method that can detect electric fire accurately is not being developed yet. This paper analyzes the cause of electric fire and the characteristics of Arc Fault Circuit Interrupter(AFCI). First this paper compares AFCI with existing molded-case circuit breaker and finds the hazards caused by arc through power calculation and compares with danger by short circuit. And we suggest the necessity of AFCI through studying relationship of AFCI installation and societal cost.

  • There are 1,550 small or large traditional markets in the whole country. They have many dangerous elements of fire, because of using various electrical products in poor and small space. Recently, government has supported the modernization of traditional market. But, only 50% of them has modernized. There has always been high level of fire risks because of the both modernized and nonmodernized facility are not fit for "Technical Standards on Electrical Facilities". Accordingly, we examined electrical facility setting and use about modernized and non modernized traditional markets which has ever been fired.

  • Purpose: Recently, in addition to increase in the use of electric ranges, fires have also been increasing. Method: To find out the fire risk of induction and highlights range, looked at the structure and operation methods. Combustion tests, heat transfer tests, and ignition tests were performed on both types. Results: The highlight electric range burned the towel two minutes later, takes about 25 minutes for the residual heat to cool down after cooking, and the energy of the red color disappeared in three to four minutes and no sparks were seen. Conclusion: Experiments have shown that burn and fire hazards exist, especially if there is cracks in the top, there is a risk of fire and explosion.
