Development of the Power Line Proximity Warning Apparatus for Mobile Crane using the Induced Voltage Measurement

유도전위 검출방식을 이용한 크레인의 고압 전선로 접근 경보장치 개발

This paper describes the power line proximity warning device for mobile crane by using the induced voltage measurement method. A mobile crane worker can be easily exposed to dangerous electrical shock and the electrocution while this are working at near the high-voltage electrical lines. In this paper, the derivation electric-potential of the power lines are simulated and microprocessor-based detecting device and transmitter/receiver modules are introduced to show a solution for the dangerous mobile crane working environment.
