Abstract

PURPOSE: To make it possible to accomplish the reliable measurement of the change-over time of a trolley line by combining the change-over starting point with the signal for detecting the finish point to measure the time interval of the change-over and by using a gate circuit, which is opened in response to the entrance warning signal to the dividing sections of the trolley line.
