DEHNproX HVD voltage detector

Detection of the dead condition – robust, reliable, smart.
The 5 safety rules applied directly in the work process.

Discover the latest state of the art technology for detection verifying the absence of voltage in medium- and high-voltage installations – the DEHNproX High Voltage Detector (HVD).

Whether it’s a substation, a switchgear installation, a power grid or railway infrastructure: Thanks to its robust operation, reliable functional performance and, for the first time, smart support, the HVD makesit easier for youto perform the detection of the dead condition in accordance with DIN VDE 0105-100.

Configurable online and designed to connect with the DEHNwork app, the new generation of voltage detectors offers greater safety in use, greater clarity for users and more support for those responsible for organisational matters.

First types up to 36 kV (available from Q3 2026)
Is configurable online (available from Q4 2026)
DEHNwork App-ready (available from Q4 2026)

Greater safety for qualified electrically skilled persons

Anyone who is responsible for people, tasks and work equipment needs safety and traceability. The DEHNproX HVD helps to make the process of checking for the dead condition more transparent and to document safety-related procedures in a traceable manner.

Greater safety for electrically skilled persons in the field

At the crucial moment, clarity is what counts. The DEHNproX HVD supports electrically skilled persons with a clear voltage indication, easy operation and reliable warnings – ensuring safety even under time pressure and in changing operating conditions.

Technical highlights of the HVD voltage detector

ROBUST in everyday use

•    Optimised operation
Slim, lightweight design, battery replacement without tools, easy to operate whilst wearing protective gloves.
•    Suitable for use in all weather conditions
within an extended temperature range of -40 °C to +70 °C
•    Can be used flexibly:
in a wide variety of working environments thanks to the plug-in coupling and extension options

RELIABLE when it matters most

• 360° all-round visual display
LED ring with red and green lights – clearly visible to everyone at the point of use

prevents incorrect use of installations operating at the wrong power frequency

• Self-test right up to the test prod
Guaranteed to be ready for use: automatic self-test, including the test prod, before every use
• Standby function (optional)
The device performs voltage detection even in battery-saving standby mode

SMART through digital support

•    Comprehensible documentation
Data from the last 30 events is stored directly in the device and can be accessed for accident analysis, for example.
•    Always up to date
Autonomous device updates can be carried out wirelessly
•    DEHNwork-app-ready
Can be used optionally in connection with the DEHNwork app for device settings, operating state indications and documentation

Triple warning. Simply safe.

Whatever work situation you find yourself in, the HVD informs you clearly if voltage is present.

The 360 ° all-round display is clearly visible from all sides – even to people standing nearby.
The warning tone can be heard clearly even in noisy working environments.
Using the DEHNwork app, the device can be easily adapted to individual requirements and operating conditions.
