Power comes from ConEd or LIPA at 13.2kv to 70kv and 60hz. In the old substations central switching station converts that power into 11kv 25hz, while a more modern system simply steps it down, then switches the 13.2kv 60hz power for distribution to substations. The power then travels through an 11kv or 13.2kv bus to breakers that control the distribution to the subsidiary substations below the central switching stations. From the breaker the power travels down the wires next to the ROW to the other nearby substations. In each substation those AC wires feed the rectifiers which turn out DC power, and that goes through more switch gear before going to the direct third rail feeder.If you wish to remove the wires parallel to the right of way then you must remove the central AC switching station and distribute that AC feed and switch gear to every single substation. |
