More Safety When Working on Electrical Installations
Accidents caused by human error, such as when an electrically skilled person accidentally approaches the wrong energised switchgear installation, can be avoided.
The DEHNsense EFD electric field sensor provides visual, acoustic and haptic warnings of the dangers of electric current by detecting a critical AC voltage and alerting the user in good time before entering the danger zone. As an additional measure to the five safety rules, the detector significantly increases safety when working on electrical systems. Accidents caused by human error, such as when an electrically skilled person accidentally approaches the wrong energised switchgear installation, can be avoided. The device can be used in both indoor installations and outdoors, even in wet weather (IP degree of protection 65). The detector is easy to operate and can be worn either on the wrist or helmet. The response sensitivity of the EFD can be adapted to the specific installation via the DEHNwork app to avoid false alarms. The app can also scan a QR code that has been generated for a specific system and transfer the individual response value to the EFD without any contact, while all important events are logged in the app for easy documentation. The portable voltage alarm can be used worldwide in electrical switchgear installations and on overhead line networks. It can be used for nominal voltages from 6 – 420 kV / 50 – 60 Hz: the system-specific response value is selected according to the conditions on site. The EFD outputs a visual, acoustic and haptic warning as soon as it detects a dangerous electric field. Although it serves as additional safety information when maintaining electrical systems, it does not replace the five safety rules as per DIN EN 50110-1 (DIN VDE 0105-100) that apply in such areas.
