Implementation of Failure Detecting and Monitoring System for High-Pressure Natrium Lamps and Ballasts

고압나트륨 램프와 안정기를 위한 고장 감시 시스템의 실현

In this paper, we implemented this failure detecting and monitoring system for high-pressure natrium lamps and ballasts. The hall CTs of the local detecting system measure the current flowing into natrium lamps via ballasts and acertain whether the natrium lamps or ballasts are out of order or not. These test data are transmitted to the main monitoring system. So, we can see the status of the natrium lamps or ballasts promptly.
