In Poland the power to the metro traction supply is provided from District Point Supply (RPZ - Rejonowych Punktow Zasilania). The transformer rectifier substations convert the 15 kV, 50 Hz to 750 V DC which is supplying the metro cars by third rail. The metro supply is “dual feed” on AC and DC side to provide backup power in the event of a fault.
