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.

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.
