Claim Text:
1. A system comprising: a voltage detector constructed to measure a DC overhead line voltage of a railway power system, the line voltage having a magnitude in excess of 1500 volts, the voltage detector located at a power supply unit of the railway power system; a current detector constructed to detect current flow of up to hundreds of amperes to an overhead line from a regenerative braking system of a train at a voltage of 1800 volts, the current detector and located at a load unit of the railway power system; a signal input unit constructed to receive signals from the voltage detector and the current detector; a signal converter constructed to convert an analog signal received from the signal input unit to a digital signal; a memory including a data storage unit constructed to store data received via the signal converter in real time; a data record unit constructed to record collected data received via the signal converter; a display unit constructed to display monitored data received from the signal converter; and a controller constructed to:
