<p>After initialization the power demanded by the traction network is measured continuously (101) and compared (102) to stored values appropriate to economic tariff operation. If consumption is too high an alarm is initiated (103) and an operator examines the system loading (104) and sends (105) pre-programmed line current limits to individual vehicles selected according to type of route, number of passengers and any lateness. An Independent claim is also included for : Equipment to measure power taken by the traction network, detect any tendency to exceed a power limit and transmit power limits to individual vehicles</p> |
