Description

DEHNdetect

Lightning current measuring system for detecting lightning events

DEHNdetect reliably detects lightning events preventing expensive
maintenance work and long downtimes. Damage resulting from a
lightning strike does not necessarily lead to the immediate failure of
the turbine and, as a result, lightning events often remain undetected.
Especially in the case of upward fl ashes the initial long stroke
current fl owing is only a few 100A and can be the main cause of
melting, e.g., on the receptors of rotor blades. The resulting subsequent
damage may be severe. The revised standard IEC 61400-24
(July 2019) Wind turbines Part 24: Lightning protection recommends
the installation of measuring systems which can also measure long
stroke currents in order to determine the intensity of lightning
strikes.

DEHNdetect not only recognizes peak currents but also these
dangerous long stroke currents and can, moreover, be equipped
with optional rotor blade detection. The system can be integrated in
the IT infrastructure of the wind turbine via existing interfaces. The
data can then simply be read out and managed using the available
SCADA systems. If direct integration is not possible, the data can be
transmitted to a cloud 1). The current curve can be evaluated in detail
in this web application. This makes it possible to monitor several
turbines or even entire wind parks.

DEHNdetect determines the following parameters:
Impulse current [kA]
Specific energy [MJ/Ω]
Load [C]
Long stroke current [A]
Rise time [kA/μs]

Your advantages:
Prevention of subsequent damage
Optimization of maintenance work and servicing
Reduction of downtime

Description

HVI lightning protection – Your benefits at a glance

  • Keep separation distances
    You install directly next to conductive structural parts or electric lines or pipes
  • Easy to mount
    With the modular components and special tools, such as the HVI-Strip, mounting is safe, quick and easy
  • Integration in the architecture of the building
    The grey HVI Conductor and the HVIlight Conductor can be painted the desired colour
  • Flexible when retrofitting
    Subsequent installation on the roof is possible WITHOUT adapting the lightning protection system
  • Use in Ex areas
    For Ex zone 2 and 22: All HVI versions
    For Ex zone 1 and 21: HVI and HVI power
