This study aims to suggest the most stable color temperature that can relieve the anxiety of passengers in case of an elevator trapped accident. The experiment was conducted on 10 adult men in their 20s. The color temperature of the interior lighting of the elevator was adjusted to four stages (3,000 K; 6,000 K; 9,000 K; and 12,000 K). Electrocardiogram (ECG) was measured and analyzed to observe the reaction of the user's autonomic nervous system decline in 3,000 K; 6,000 K; 9,000 K compared with 12,000 K, where a statistically significant difference was recognized (p < 0.01). Among them, the activity of the sympathetic nervous system was the lowest under the condition of 3,000 K. Through this study, it was found that the color temperature of 3,000 K induced a sense of stability among passengers in the event of an elevator jam. If the results of this study are used, it seems that the stability of passengers will be secured in the event of an elevator jam.

The number of elevator installation increases every year about 15,000. The number of confine-disease of elevator increases every year and then sudden in, sudden stop, error of level indication, stand; those can bring to uneasiness of elevator passenger and malfunction related life accident is increasing. Therefore we researched elevator repair diary of elevator repairing company, APT management office and 119 life rescue for elevator confine-disease during 2004. 1. 1.${\sim}$12. 31. we analyzed the content and the time type and cause of the malfunction and fault for APT elevator. Form the result of 119 life rescue, only power reset is 24[%] and only power failure is 8.2[%] by cause of confine-disease. This paper will be used data of the analysis for mutual relation between Power Quality and malfunction and fault of elevator.

The number of confine-disease of elevator increases every year and then sudden rise, sudden stop, error of level indication, stand; those can bring to uneasiness of elevator passenger and malfunction accidents related life accident are increasing. For confirmation those malfunction accident, we are measuring and analyzing power quality(Sag, Swell, Interruption) of the actual site and evaluated the performance for stop and stating by testing the two imitation test equipment with EN12016(2004) standard level. This paper will be used data of the analysis for mutual relation between Power Quality and malfunction and fault of elevator.

The number of confine-disease for elevator increases every year and then sudden stop, error of level indication stand; those can bring to uneasiness of elevator passenger and malfunction accidents related life accident are increasing. So we researched power quality counterplan equipment(SPD, Filter, Reactor) at site elevator controller room and malfunctions of elevator movement. We could confirm installation of power quality counterplan equipment recently and unchanging the number of malfunction. This data will be used the analysis for mutual relation between Power Quality(Sag, Interruption, ESD, ect.) and malfunction of elevator movement by testing the elevator equipment with EN12016(2004) and IEC standard level.

The malfunction accidents such as kept within elevator, sudden rise, sudden stop, error of level indication which can bring about uneasiness of elevator passenger and be related with life accident are occurring. However, as there is not field recurrence for this portion and they are accidents that occur and then disappear, it is actually difficult to confirm the reason of accident. Therefore, we made an experiment for tolerance in three models which is being built recently according to EN12016(2004) standard and analyzed the movement characteristics of elevator to study the reason which can bring about confine and malfunction. Furthermore after supplementing measures for malfunction, Finally this paper will be used as reference to suggest methods for malfunction of elevator facility and the analysis for mutual relation between Power Quality and malfunction and fault of elevator.

엘리베이터는 국내의 빠른 성장과 함께 급속도로 보급되고 있는 수직 형 교통수단으로 국민 대다수가 이용하고 있다. 엘리베이터의 빠른 보급과 함께 여러 가지 원인에 의해 엘리베이터에 갇히는 사고로 인하여 승객의 불안감을 유발시킬 수 있는 부분이 많이 증가하고 있다. 따라서 본 논문에서는 공동주택 엘리베이터에서 이런 갇힘 및 오동작 등을 발생 시킬 수 있는 Surge, Sag, Interruption, Noise(Harmonic) 등의 유입에 대한 대책으로 엘리베이터 설비에 어떤 보상 및 대책 장비들이 설치되어 있고 그 사양 및 현장 설치 시설에 대해 조사 분석 하였다. 조사한 장소에서 대부분이 서지 보호 장치, 노이즈 필터, AC Reactor의 설비 설치가 미비하였다. 조사된 자료는 공동 주택 엘리베이터의 전기적 장해원인 분석 및 대책을 제시하는데 자료로 이용될 것이다.
