Current issues

Reliable detection of long stroke currents in wind turbines with DEHNdetect

Avoid expensive maintenance and long downtime.

The problem: as it does not necessarily lead to the immediate failure of the system, damage caused by lightning often remains undetected in wind turbines. Initial long stroke current of only a few 100 A is frequently the chief cause of damage, e.g., melting on the receptors of the rotor blades. In the long term, this damage can lead to system failure.

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.

DEHN Safety Equipment Portfolio

 

Protect your system - With the technically highly developed DEHNshort protective system you have arc faults firmly under control and can keep downtime to a minimum.

 

Protect your employees - You can keep your employees safe by providing optimum DEHNcare personal protective equipment and suitable safety devices for live working.

Arc fault protection = system availablity

DEHNshort, the arc fault protection system, provides reliable protection for switchgear assemblies up to 110 kA - 690V. The modular system is individually configured to suit the assembly at hand. With arc fault quenching times of just a few milliseconds, it is one of the fastest protection systems on the market.

The most common causes of arc faults are

  • errors made when working on the switchgear assembly
  • soiling
  • foreign objects like forgotten tools
  • animals which find their way into the assembly

This means that there is always a risk, even in the most modern switchgear assemblies.

An arc fault protection system offers you safety and the highest possible system availability.

Safe service and maintenance work

Work on electrical systems is extremely demanding. Your workers have to be highly concentrated and very cautious at all times.

Personal protective equipment PPE helps prevent life-threatening injury, as far as is possible. A complete set of equipment consists of a jacket, trousers, gloves, safety shoes and head protection including a face shield. All materials must be flame and heat resistant, insulating and completely cover the skin.

Provide your employees with equipment which offers them the best possible protection aginst arc faults.
