| Özet: |
Most of the modern DC electrified mass transit systems use a
totally floating earth as their grounding strategy. A well known problem
related with totally floating systems is that the touch potentials can be
dangerously high. In order to reduce the voltages on rails, several
devices exist. Most of these devices allow a direct connection to earth
when a certain voltage threshold is exceeded. In this paper, working
principals of these devices are given and the effect of certain parameters
related with these devices on the minimum achievable touch potentials is
investigated. |
