DEHNsphere – the digital resilience platform
Know what's happening to your asset – as it happens
DEHNsphere is the digital resilience platform for critical electrical infrastructure. As an IoT cloud platform it connects to smart field devices to continuously monitor lightning events and the condition of electrical systems.
All collected operational data is consolidated in a central dashboard and transformed through cloud-based analytics into actionable insights, alerts and recommendations. Whether you operate wind turbines, power grids or industrial facilities, DEHNsphere enables faster, informed and compliance-driven decision-making across geographically distributed assets.
Protection becomes proactive resilience – delivering greater operational reliability and measurable business value. Use DEHNsphere to minimise risk, prevent unplanned downtime and increase the availability of decentralised asset portfolios.

DEHNsphere plus DEHNdetect. Smart Monitoring solution for the wind industry.
The DEHNdetect lightning current measuring system was specifically developed for wind turbines and is installed directly inside the turbine as a compact box solution. Using a Rogowski coil, it detects both cloud-to-ground and upward lightning strikes. Blade Detection Units (BDUs) enable the direct assignment of a lightning strike to the affected rotor blade.
The DEHNsphere cloud wirelessly connects to the measuring system DEHNdetect. Through the digital IoT platform, operators gain real-time visibility into all lightning events detected by DEHNdetect and their impact.

Answers to frequently asked questions about DEHNsphere
1. Why should I install a lightning monitoring system?
Lightning activity can significantly affect the availability and security of critical infrastructure. DEHN smart solutions provide transparency regarding the impact of lightning on your systems and help operators to reduce risks, avoid unscheduled downtimes and improve the reliability of distributed infrastructure.
2. What are the main benefits of smart monitoring for plant operators and owners?
DEHNsphere converts raw data on lightning and overvoltage events from networked devices into actionable insights. This means operators can reduce risks, increase availability and manage critical infrastructure more efficiently – with the following key benefits:
- Immediate insights into lightning events and their intensity
- Fewer unplanned downtimes thanks to targeted inspections
- Less maintenance and reduced costs
- Centralised monitoring across multiple sites and assets
3. What does DEHN offer in the field of smart monitoring?
DEHN offers a range of smart monitoring devices for various market segments and applications that can be connected to the DEHNsphere resilience platform. The range extends from individual smart devices to fully managed end-to-end solutions.
4. For whom is smart monitoring particularly relevant?
The solution is aimed at operators and owners of critical infrastructure for whom high availability, safety and resilience is crucial.
Typical areas of application include:
- Power suppliers and grid operators
- Wind and solar power plants
- Industrial plants and production sites
- Critical infrastructure such as data centres and transport systems
- Insurance companies and technical assessors
