Energy Suppliers

Energy suppliers show especially great interest in accurate lightning information. For the most part, they require the entire spectrum of lightning data since lightning strokes are one of the most frequent causes of serious malfunctions.

The advantages

    • real-time evaluation of malfunctions caused by storms
    • estimation of impending interruptions to operations caused by storms
    • evaluation of lightning-protection measures
    • evidence of lightning-induced damage

    ”As a regional power-grid operator, LEW Verteilnetz GmbH sets great store by efficient processes and exceptional supply quality. With the precise lightning data supplied by nowcast, we are able to reliably identify lightning-induced failures immediately. In this manner, we have been able to reduce the downtimes of our medium and high-voltage transmission lines.“

    German Semsch (Verteilnetz GmbH, Head of Network Management Central)

    Efficient surveillance of transmission lines and pipelines

    Operators of transmission lines and pipelines feed the numerical lightning data in real-time into their control-station software. In the event of a malfunction, the software carries out an automatic check as to whether a lightning stroke has taken place in the vicinity of the affected transmission line or pipeline at the time in question. This simple procedure reliably identifies this frequent cause of failures and normally allows for the prompt resumption of operations.

    Railway companies are also confronted with the same issues. The comprehensive surveillance of the rail network also includes the fault-monitoring of overhead-cable malfunctions caused by lightning.

    Optimized planning of repair and maintenance works

    When it comes to outdoor work, storms constitute one of the gravest threats to people. This is true not only of works on transmission lines or transformer stations. Oil rigs and pump stations, as well as mines and strip mines, are all locations which are affected by lightning at an above-average frequency.

    With the extremely short-term forecasting (Nowcasting) by LINET, storm cells can be projected into the future by up to one hour. Since storm cells, unlike rain and cloud fronts, are mostly limited in dimension with clear-cut boundaries, the impending danger can be forecasted with a considerable degree of precision.

    Reliable lightning information also serves optimized planning when it comes to supply lines via air or water.

    Assessment of operational malfunctions

    In addition to ensuring operational safety, users of the extremely short-term forecasting can also evaluate the interruption to operations caused by storms. Heavy storm fronts moving in the direction of transmission lines, transformer stations, pipelines or mines can be detected without delay. The patented 3D-measurement technique even makes a forecast on the severity of the storm possible.

    Should operations have to be suspended due to a storm, the forecast allows for the precise estimation of the downtime and can possibly prevent an unnecessary interruption to operations. For particularly sensitive installations, the forecasting process can be further improved with a locally installed electric field meter.

    Significant improvement of lightning-protection measures

    With the aid of historical data, expensive lightning-protection installations may be evaluated and adapted accordingly. Detailed flash-density maps, which are precisely customized to your marked-out routes, serve the easy identification of the sections affected.

    Evidence of damage by lightning or overvoltage

    By means of the historical data stored, damage induced by lightning or overvoltage can be proven after the incident in question. This serves not only as evidence for insurance purposes, but also the assessment of the lightning-protection measures taken.
