Protection in case of direct lightning strikes and transient surges

Lightning is particularly likely to strike wind turbines due to their exposed location, height and complexity.

As lightning strikes often cause considerable material and economic damage, it is important to protect your turbines. The chief objective is to prevent lightning from damaging the rotor blades, bearings and electrical systems. Permanent availability is the top priority, both for on- and offshore wind turbines.

 

DEHN your strong partner - everything from a single source

DEHN has more than 20 years' experience in protecting wind turbines and is the perfect choice if you are looking for a strong partner. Benefit from the synergies of a one-stop provider - products and services, all from one source.

DEHNdetect

Avoid expensive maintenance and long downtime. With DEHNdetect you can keep an eye on all the parameters of a lightning event. Decisions about maintenance work or servicing 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 availability

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.
Arc fault protection with DEHNshort

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 against arc faults.

DEHNcare PPE

Personal protective equipment (PPE) to combat the thermal effects of an arc fault.

Voltage detectors

To verify on all poles that no voltage is present (dead condition) in the work location.

EaS Devices

For earthing and short-circuiting electrical installations as well as accessories and components for low voltage systems.

Fixed ball points

For fixing cable lugs or conductor bar connections in place according to DIN 43673-1
