INVESTIGATION OF VOLTAGE TRANSIENTS AND SPIKES IN DIRECT CURRENT RAPID TRANSIT SYSTEMS

Voltage transients and spikes have been investigated on five existing rail rapid transit systems to define the power environment in which new rail transit cars might be expected to operate. A final report describes and evaluates observed third-rail shoe transient and spike voltages, measured in subway installations in Philadelphia, New York City, Boston, Cleveland, and Chicago during rush and non-rush hours. It condenses these data into curves which may be used as the basis of a general performance specification. The underlying theory as well as special test equipment used during the field test activity is described in detail, together with a special computer program required for test data evaluation. The results obtained may be applied to future subway car speed control systems using static power conversion.
