Preliminary study on factors of fault alarms by insulation monitoring devices on premises based on data from maintenance business systems

摘要

This paper investigates statistical relationship between alarms from monitoring devices on premises and inspection data in order to improve work efficiency of electrical safety service. In the safety inspection of electrical facilities, insulation monitoring is expected to systemize correspondence judgment based on data such as measured leakage current. In this study, leakage current observed in periodical inspections stored safety maintenance systems and alarm form insulation monitoring systems are analyzed as important information on electrical safety.
