Spot check for partial discharges in a matter of minutes
Online partial discharge testing without interrupting operation
Distribution network operators use partial discharge testing to determine the condition of their cable routes and to detect hidden faults at an early stage. As this measurement typically requires the route to be switched off (at least for a short time), network operators usually only employ this method on part of their cables.

Fault location on long power cables
Findings and experience concerning the use of submarine cables for long land connections
In a few years’ time, high-voltage cables hundreds of kilometres long and extending from one end of Germany to another will become part of the country’s critical infrastructure. Maximising the availability of these cables is crucial, so any faults need to be located swiftly and reliably and the cables repaired with minimum delay. This goes beyond the capability of conventional fault location technology but, fortunately, special solutions are available for extra-long cables based on technology partly derived from a field in which long cables are commonplace: submarine cables.

Paper
Statistical approach to condition assessment and estimation of remaining life of medium voltage cables (Part 3)
The comprehensive understanding of the remaining life time of medium voltage cables was the key motivation for extensive cable diagnostics performed by the Korean Electric Power Corporation (KEPCO). Since 2011 more than 15,000 cable routes were diagnosed to assess the cable condition. A unique algorithm and evaluation logic was developed for accurate estimation of the remaining life time of XLPE power cables. The approach was evaluated over the past two years leading to appropriate assessment results. A study on the applicability of this methodology on other utilities network is shown in this study.

More confidence in medium voltage cable diagnostics - assessment logic and strategic approach (english)
Cable diagnostics based on VLF TanDelta and VLF Partial Discharge measurement is most beneficial, when clear application procedures for new installations, for maintenance test after repair and for regular inspection [Figure 1] are defined and evaluated in network tailored evaluation logics using clear action plans. The remaining lifetime estimation is the latest software invention and allows investment planning for asset managers. Huge saving potentials are realistic when the underground medium voltage cables can be operated to the optimum lifetime, while the reliability of the network is increased at the same time.

Fault Location on Long Submarine Power Cables
The paper summarizes the main fault location techniques that can be used for cable fault location in long submarine cables depending on the various types of faults. It is shown that advanced instruments, detecting techniques and skilled crew are required in order that the detection can be effective in the various cable fault conditions. Measurements performed in field shows that a fault location system especially designed for very long cables can detect faults with a good error accuracy helping in this way to reduce the outage time for repair activities. The hazards for operators and instruments connected to the huge amount of electrical energy that may be stored in very long links are also tackled in the paper (source: © CIGRE 2014).

Combined Application of Diagnostics Tools for MV Underground Cables
This paper presents the advantages of the application of the combination of offline and online diagnostic tools for underground medium voltage cables. Partial Discharge (PD) online measurement is a useful tool to identify PD activities without the shutdown of a cable circuit. Advantages and challenges of PD online diagnostics combined with the advantages and strengths of offline VLF tan delta and VLF PD measurement are demonstrated by practical case studies. The combination of advanced diagnostic tools allows asset owners to implement condition based maintenance measures most cost and time efficient.

VLF sine 0.1 Hz – Universal voltage source for testing and diagnostics of medium-voltage cables
The use of a VLF sine voltage source opens up the possibility of a single person performing cable testing and diagnostics of a cable route and with portable equipment. In scientific studies and in the field, the VLF sine showed that it is a suitable voltage source for cable testing, PD and tan delta measurement and that the achieved measurement results can be compared with results of tests performed at operating frequency. In addition, the ideal, load-independent sine form proved to be of benefit when it pertains to the reproducibility of results and when load-independence is desired (independence from measurement of cable lengths). Thus, comparisons of measurement results can be performed easily and more experience on condition evaluation of cable routes can continue to be acquired.

New Enhancements for Cable Fault Location
Even with ever improving cable technology and broadly adopted diagnostics tools, classic cable fault location applications remain a daily challenge for distribution grid operators. A benchmark study shows that operators face about 8 MV-faults per 1000 km line length every year. New enhancements focus on supporting users and organisations of powerful test equipment better. This means support not only for the specific measuring task but support a long the complete job from assignment to repair and final report. A practical case from winter cable fault location in the swiss alps illustrates the practical challenges.

Fault finding in the interior of a mountain:
Cable fault location in the pump-fed power station
Robert L’Eplattenier, test engineer and CEO of Gasenzer AG, often travels “in the field” and is even more often in the Swiss mountains.
Customer:
Gasenzer AG, based in Hinwil in Switzerland, specialises in measurement technology and measurement services relating to fault location, testing and condition evaluation of cable systems. The company, which has been operat-ing as a joint stock company (AG) since 1991, has more than half a century of experience. In 1961, electrical engineer Hans Gasenzer established a private company that focused on cable tests and on selling specialist measuring devices. Gasenzer established a close relationship with BAUR right from the beginning and is the exclusive trade partner for BAUR devices in Switzerland.
BAUR solution:
High-resistive faults are made visible with the SIM / MIM method (Secondary Impulse Method / Multiple Impulse Method). Here, the high-resistive fault is „ignited“ by a high voltage impulse and thus is temporarily low-resistive. This helps determine the distance to the fault. This is evaluated and displayed by the device software, e.g. by the Syscompact 2000 or Syscompact 3000 software. The SIM and MIM methods have proven to be particularly advantageous because they help pre-locate faults in up to 98 % of all cases.

VLF testing on the electricity cable of a dredger
The objective of Gasenzer AG from Hinwil while checking an undersea cable in Lake Lucerne in Switzerland was to prevent any potential consequential damage. A transformer in the substation had exploded. It was assumed this had been caused by a damaged cable, as the undersea cable connected to the transformer supplied a dredger and was wound and unwound according to the position of the dredger. The Gasenzer AG engineer first used the measurement technology of the BAUR cable test van to test the cable insulation before carrying out an echometric analysis. Neither showed any signs of a cable fault. Then a subsequent test conducted using the BAUR viola testing device.
