DCC DC VOLTAGE DETECTOR

This device is used for proving dead operation of direct current overhead conductors, especially railway catenary (metro, trains).

• Detection of DC voltage (presence or absence of voltage).
• Detection of residual DC voltage measures the unloading of the line.
• Detection of nominal or induced AC voltage (presence or absence of voltage).

Advantage

• Avoids false nominal DC voltage detection: Double measurementcircuit to discriminate nominal voltages from stray voltages coming from surrounding circuits.
• Permanent checking of the earth leads Permanent checking of the continuity of the earth lead.
• Direct access to the battery and sealed electronics compartment.
• When the battery is replaced, this design prevents the following.
  • Damage to electronic circuits
  • Humidity ingresses the device when the battery is replaced outdoors.
• An optimized indication that can be clearly identified in all working conditions.
  • The indicator light is visible in all usual working environments, in sunlight or fog, with a wide visibility angle.
  • The 100 dB sound signal (from 1 meter) is audible over traffic noise or strong wind, thanks to natural conduction by an acoustic “horn”.

• Full self-test with self-test button including continuity checking of the lead, battery level and low battery indication.
• Dedicated display for each function clear information.
• Warning for overrated voltage range 5000 V) visual and continuous sound indication.
• A current limitation in the cable is below 3, 5 mA.
• Up to 36 kV surge voltage withstanding.
• Robust shell with shock-absorbing adapter, range of adapters available on request (U, APV R).
• Counter nut allowing the electrode to be locked in any direction.
• Ergonomic button adapted to operation with insulating gloves.

Technical Specifications
