Analysis and Rectification of High Zero Ground Voltage in Instrument Landing System Equipment Room
The instrument landing system(ILS)is a navigation equipment that provides important guidance signals such as glide slope and localizer during aircraft takeoff and landing.The ILS equipment at Zhuhai ATC Station No.05 and No.23 plays a crucial role in the safe approach and landing of flights at Zhuhai Airport.The power sup-ply and distribution in the equipment room are directly related to the safety of civil aviation ATC.This paper com-bines the problem of high zero ground voltage in the ILS glide slope machine room at No.05,to explore the causes of zero to ground voltage,the impact of high zero to ground voltage,troubleshooting methods and prevention and con-trol measures,so as to provide reference for solving similar problems.
