Prevent expensive maintenance work and long downtimes.
The problem: Lightning damage frequently remains undetected in wind turbines as it often does not lead to the immediate failure of the system.
Upward lightning with an initial long stroke current of only a few 100A is the chief cause of damage such as melting on the receptors of the rotor blades.
In the long term, this damage can lead to turbine failure.
Whether onshore or offshore: A lightning current measuring system is indispensable for wind turbines. If a lightning event is not evaluated in detail, downtime and unnecessary repair costs may be the consequence. What does this cost? Time, resources and a lot of money.
DEHNdetect sends lightning data in real time allowing you to specifically plan maintenance and service activities.
Your advantages:
Why a lightning current measuring system? What are the benefits of DEHNdetect? Which components does the system consist of?
In this video, our expert summarises the most important aspects of the DEHNdetect lightning current measuring system in just a few minutes.
(Note: Video WindEnergy Hamburg 2020)
With DEHNdetect you can keep an eye on all the parameters of a lightning event.
Decisions about repair jobs or servicing work are then based on detailed information rather than gut instinct.
All important data at a glance
The DEHNdetect lightning current measuring system registers long stroke and impulse currents. Following a lightning event, you automatically receive an e-mail with detailed information. The rotor blade detection tells you exactly which rotor blade is affected. This optimises the preparation of maintenance work and avoids wasting time.
Data management in the cloud...
Very practical: All the data is transmitted to a cloud, either via the local network of the wind turbine or a mobile connection. Here you can display all the available lightning current measuring systems individually and read out and manage the parameters.
The possibility of connecting with various monitoring systems means that you are flexible, now and in the future.
... or on the company server
You would prefer to send your data to the company server than to a cloud? This does not present a problem either.

This monitoring system keeps you in the picture. Whether for an individual turbine or a whole wind park, with DEHNdetect you always have data on the condition of your components close at hand.
DEHNdetect consists of
A - Up to 3 rotor blade detectors
B - Measuring coil ICC IMP
C - Data logger and integrator
It identifies the affected blade and notifies you in the SCADA system or online.
Choose the right installation point of the coil
Data logger with different interfaces for integration into IT systems.
Processing of the measuring signals and transfer to the data logger.
DEHNdetect ICC IMP
Rogowski coil for measuring long stroke and impulse currents, measuring range 60 A up to 250 kA.
Detector for the wireless detection of the lightning current in the rotor blade.
You want to use Modbus as an easy and convenient way to connect the DEHNdetect to an INSYS icom router? Ready-to-use configuration files for this purpose are available in the download area. These already contain all important Modbus registers required for your application. Simply upload the corresponding file in icom Data Suite and you're ready to go.
For example, you can integrate the DEHNdetect into a SCADA system via the IEC 60870-5-104 protocol.
