This study researched the mutual relationship between elevator emergencies(sudden stops, entrapment) and power quality such as voltage interruptions or sags. To analyze the power quality at the elevator switchboard of an apartment, the on-line power quality(sag, swell, and interruption, etc.) were measured and error messages(under voltage error, etc.) in the elevator control room were researched. Also the performance and susceptibility for stops were evaluated and stated through the testing of three pieces of simulated test equipment with an EN12016(2004) standard setting and the magnitude and duration data of the measured sag or interruption. This paper will use these data in the analysis of the mutual relationship between power quality and elevator emergencies.

Domestic elevator accidents which are related to human life such as death are occurring steadily. This research measured and analyzed for the quality of power source which has possibility to be associated with fault and malfunction of elevator equipment although it is not direct cause examination. In conclusion, we acquired the result that there is possibility that the quality of power source(Sag, Interruption, Harmonic, Electromagnetism emission waveform, Static electricity etc) has an effect on movement of elevator through examination of three elevator facility models and suggested measures for it. Accordingly, this research result will be used as data to suggest establishment of elevator examination regulations and KS regulations for domestic elevator industry and the least safety of household using elevator.

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.
