PTT - Tramway Traction Rectifier

PTT - Tramway Traction Rectifier

Based on years of experience in designing and building rectifier stations, we have expanded our product portfolio with a modern and reliable 12-pulse diode rectifier (PTT) designed for powering DC traction systems. Depending on local conditions, the PTT rectifier is available in two configurations:

  • compact (rectifier mounted on the transformer),
  • free-standing.

 

The PTT rectifier is equipped with an advanced control system that ensures, among others:

  • fault detection signaling for diode short circuits,
  • capability to measure output voltage and current,
  • temperature measurement in the rectifier assembly and inside the transformer using PT100 or PT1000 probes,
  • interfaces: 2x CAN, Ethernet, RS485, as well as relay outputs and digital inputs,
  • intuitive user interface.

 

Key parameters of the PTT rectifier:

  • nominal rectified voltage: 660 V,
  • nominal rectified current: 1200 A,
  • overload classes: V and VII according to PN-EN 50328.
