Protect your investment. From the very beginning. Commissioning testing, cable diagnostics and cable fault location on underground and submarine cable installations in wind farms and PV plants, and for HVDC interconnectors

THE COMPLETE 360° SOLUTION Commissioning tests, cable diagnostics and fault location on wind turbines and PV systems Power cables form the backbone of our energy supply chain, now more than ever when considering the ongoing ‚green‘ transition of power grids and the fast expansion of renewables. Keeping these cables in good condition is essential for ensuring cost-efficient and reliable operation over many years. Inspecting the outer sheath is the easiest way to obtain valuable information about the condition of a cable. If the sheath is intact, water cannot enter the cable and there is no risk...

COMMISSIONING TEST AND DIAGNOSTICS After installation, during periodic maintenance, after repair, at the end of the warranty period, or at asset handover In accordance with DIN VDE, CENELEC, IEC and IEEE Before a wind turbine or photovoltaic system is commissioned, the cable installation going to the substation must be tested according to relevant standards. The same applies after repairs have been carried out. This allows to detect weak spots in terminations and joints or damage to the main insulation and outer sheath at an early stage, meaning, they can be remedied by way of preventive maintenance...

SYSTEMATIC CABLE FAULT LOCATION ON LONG SUBMARINE AND UNDERGROUND CABLES Assembly errors and external damage caused by third parties are the most common failure modes of cables. Cable faults are associated with long downtimes and operators‘ losses can easily run into the millions. Investing in suitable fault location equipment and having the equipment readily available if faults occur reduces downtimes significantly. Due to such time savings the investment will pay for itself very quickly. Insulation and sheath faults Shorts Earth faults Breaks Intermittent Moisture

VOLTAGE / POWER High performance cable fault location system Can be integrated into a seaworthy maritime transport container. Stationary systems at each end of the cable significantly improve the measuring accuracy on very long cables CENTRIX EVOLUTION R30 2.0 OFFSHORE CONTAINER Centrally controlled cable test van Suitable for all cable networks up to transmission level. Flexible to meet customers’ needs; can even be integrated into small vans Mobile cable fault location system Offers the same ease of use, performance and safety features as a cable test van – while being lightweight and taking...

World record! The Teleflex VX radar performed with great success on a 580 km long submarine cable between Norway and the Netherlands For the first time, a 580 km submarine cable has been successfully measured over its entire physical length using a radar or time domain reflectometer. The NorNed HVDC submarine cable is one of the longest submarine cables in the world and runs from Norway to the Netherlands. Precise fault location technology like this is already of vital importance for operating the NorNed cable and generally all other submarine cables in an economical way. TDR technology is a...

The TDR tester with an extended range is optimised for working on long cables

Pioneering and applying latest technology to have success in challenging cable fault scenarios The construction of offshore grid connections and long underground cables is progressing steadily. However, faults in submarine cables differ greatly from those in underground cables, because it is not possible to exactly pinpoint faults in submarine cables under water. Nevertheless, those cable faults must be remedied in record time. For this, Transmission System Operator TenneT contracted the KOOPMANN Group to collaborate with Megger in the development of a suitable concept. The result is revolutionary:...

The control room in the container offers enough space for several people The excellent performance of the last few years – with more than 30 offshore operations and a 100% detection rate – shows that our expert test engineers have chosen the right technology.

Unbeatable sheath fault location... The company Hennig KMFO has been a specialist in cable testing according to VDE standards for several decades. A new wind farm needed to be connected to the local grid of a municipal utility, and the utility company demanded a thorough withstand and sheath fault test to be carried out beforehand. This proved to be fortunate because the testing regime immediately revealed various sheath problems and ground faults on the cables.

... whether in a wind farm or PV system

Reliably protecting wind farms against cable faults wpd windmanager is the first wind farm operator who have got their own cable test van. Since then we have been locating cable faults in those wind farms entrusted to us, as well as diagnosing defects and weak spots long before they would fail. We are thereby protecting investors from expensive asset damage, ensuring profits and return on investment. We chose Megger due to the special technologies employed in cable fault location and diagnostics.

Innovative measurement technology, in conjunction with great support from Megger, helps us obtain meaningful measurement results. Oliver Klausch Head of Technical Management at wpd windmanager
