In preparation for the show, we interviewed one of our most experienced test engineers to provide you with the most important information about DGUV V3 testing for wind turbines. In this interview, you will learn everything about the scope of the audit, the qualifications of our employees and the duration of the audit. Take the opportunity to meet us in person at the trade fair and make an appointment for a consultation!
Our Expert: Kevin
Small
Master
of Science (M.Sc.) in Wind Engineering, expert in DGUV V3 testing and
Electrical engineering in the wind energy industry.
Since 2019 experience in the implementation of low-voltage and
medium-voltage tests and switching operations. Certified EFK
(Electrician) specialising in DGUV-V3 and switching operations in the
medium voltage range.
Question
1: What tests do you offer as part of the DGUV V3 examination?
Kevin
Small:
This is one of the most frequent questions from our customers. The DGUV V3 test includes
a variety of tests to ensure that your wind turbine meets the
legal requirements. We don't just test the electrical
safety of the wind turbine, but also the medium-voltage turbines
and protective devices that are essential for the operation of the entire plant. One
a frequently mentioned topic is also the transfer station (ÜSt): Here we offer
a comprehensive audit to ensure that after the shutdown of the
medium-voltage system, all relevant components, such as fuses and cables,
be tested for their function. In this way, we cover the entire
test requirements and ensure the smooth operation of your wind turbine.
New
the portfolio includes the testing of the external lightning protection system in accordance with DIN EN
61400-24. This includes resistance measurement or continuity testing
from nacelle to earth connection lug in the base of the tower, divided according to design into
Individual measurements, e.g. for spark gaps. Once the check is completed, you will receive
the customer has a separate lightning protection protocol.
Example
from practice:
Recently, we carried out a wind farm inspection, where the
Cable paths of the switchgear checked. Different fields are examined here,
including the transformer. These cables are basically never tested because this is not the case.
is prescribed. Fortunately, the customer insisted on it and so
defects were discovered and a fire within the plant was prevented.
Question
2: What qualifications do your employees bring to the DGUV V3 exams?
with?
Kevin
Small:
The qualification of our staff is the key to a successful
and safe testing. All of our test engineers are trained
Qualified electricians (EFK) with years of experience in the testing of
Wind turbines. Our teams not only have extensive knowledge in the
electrical engineering, but also have specific training for
Switching operations on medium-voltage systems. They work with state-of-the-art
Measuring equipment, such as insulation measuring devices and protective relay testing devices, in order to
ensure accurate and reliable results. This expertise enables
enable us to inspect even complex systems efficiently and safely.
Concrete
Qualifications:
Our teams regularly submit proof of training and conduct the exams
for over ten years. This includes not only the audit itself, but also
also the trained eye for potential vulnerabilities that other
possibly overlooked. We cover over 90% of the plant landscape.
Tip
for operators:
When choosing your testing partner, make sure that the auditors
are demonstrably qualified and have experience with the specific technique
of wind turbines. An incorrectly executed inspection operation can
cause expensive follow-up costs.
Question
3: How long does the audit take and when will the reports be available?
Kevin
Small:
The test duration depends on the size and complexity of the wind turbine,
an old system or a new system that contains many electrical components in
hub, but we usually manage up to three
On-site inspections. If major defects or safety-related problems
we will inform the operator immediately in order to provide rapid
to initiate countermeasures. The goal is to get the plant up as quickly as possible
safely put back into operation. The test report, in which all the results
is usually within working days

What
What happens in the event of defects?
If we find defects on site, we discuss them directly with the customer
and provide recommendations for remediation. Recently, we were able to
early detection of corrosion damage to a cable route is a potential
critical situation – and without much disruption to the
