In this report we developed a high voltage alarm for the safety of workers who check and repair the 154kV power line. This high voltage alarm we developed is attached on workers' helmet and alarms automatically in order to let workers know when workers work over the safety distance near 154kV power line. Until now the exact safety distance hasn't been regulated and high voltage alarm we've been using was for the range of 6∼22.9kV power line. We fabricated this high voltage alarm on the basis of electric density and actual measurement of power line. The experimental result was that high voltage alarm at 66kV power line alarmed near 90cm, at 154kV power line alarmed near 160cm from the line.
Accordingly, we developed the new high voltage alarm which is operated in the range of 66∼154kV power line.
