PBwel is the leading designer, manufacturer and supplier of quality electrical safety products.


This device is used for no Voltage Testing of direct current overhead lines (mainly transport overhead lines: trams, metro and trains).

  • Detection of DC voltage (presence or absence of voltage)
  • Detection of residual DC voltage (measure the unloading of the line)
  • Detection of actual and induced AC voltage (presence or absence of


  • Setting the threshold by self-learning on real voltage (MCU)
  • Robust shell with flexible adapter coupling (AFLEX)
  • Full auto control with self-test button (cable is also tested)
  • Dedicated display for each function clear information
  • Warning excess voltage range 4000 V) visual and continues sound indication
  • A current limitation in the cable below 3 5 mA
  • Surge resistant up to 36 kV

Technical Specification
