Seoul Metro and Seoul Metropolitan Rapid Transit Corp. have started installing screen doors at subway platforms to improve the environment of subways and prevent passengers' accidents since 2006. They are still installing screen doors at subway platforms and Metropolitan Rapid Transit Corporations in other areas are also proceeding with installment of screen doors or making preparations for it. Grounding is necessary for installing PSD systems. In case that PSD grounding is connected with existing electrical equipment grounding system, it was decided to install separate grounding for safe operation of PSD system and passenger safety. However, it's very difficult to install new grounding at the subway station compound. A way to improve this condition is that we proceed with grounding by composing grounding station by carbon grounding rod.
This paper will mainly deal with how to design and construct carbon ground rod, which has been applied to PSD system grounding since 2006, including its experimental examples. In this paper, ways to secure ground resistance below 5 ohms, which is resistance necessary for PSD grounding, and to compose grounding system were also discussed. Furthermore, a ground test to check the ability to fulfill a role of PSD grounding system was conducted.
As a result of applying carbon grounding module, PSD system is being operated without any problem and the installment of PSD system will be continuously expanded in the future. It's also thought that a way to integrate grounding of each functional room which has been installed at the subway station compound and to arrange equipotential grounding should be reviewed and performed promptly.
