Vaisala FALLS (Fault Analysis and Lightning Location System) is user-friendly client/server software that allows utilities, wind farm operators, and other commercial operators the ability to easily determine if lightning has affected an asset. Quickly analyze events and access historical lightning data for both near-real time and past occurrences. FALLS Client software allows you to be proactive in your approach to determining damage caused by lightning. The software provides the ability to quickly and easily perform fault correlations on an event-by-event basis, obtain statistics concerning the number of lightning events or magnitudes for design, and evaluate lightning challenges to an asset (e.g. a power line or wind turbine) or an area, for input to maintenance prioritization.
The FALLS® Server is the lightning data management processor module that receives and stores real-time lightning data from the Vaisala Thunderstorm central processor. Vaisala Thunderstorm Information System operators use the FALLS® Server to archive their lightning data into a relational database. Users have easy and secured access to the archived data for use in their lightning display software and lightning analysis software. The FALLS® Server also provides secured access to real-time lightning data.
Vaisala FALLS® Server allows flexible and efficient manipulation of lightning data through a published set of industry standard Structured Query Language (SQL) function calls and procedures.
Vaisala FALLS® Client is innovative software used by electric utilities, wind farm operators and others, to query previously recorded lightning information in a GIS (Geographic Information Systems) environment. The Vaisala FALLS® Client software generates lightning information into maps, graphs, and statistical tables, and is used to analyze the impact of lightning on assets and systems. Whether you are investigating suspected lightning-caused faults or are studying the climate of your service territory, Vaisala FALLS® provides an easy-to-use platform to quantify and prioritize recommended protection investments.
A Reliability Analysis maps event-specific lightning analysis in near real-time. It locates poorly performing asset segments or system weaknesses, validates your lightning protection design and correlates your asset faults to lightning activity or a lack of lightning activity.
A Regional Analysis generates regional and local lightning discharge occurrences and/or densities for user-specified time periods. It is used to identify hot spots for lightning activity, compare variations in lightning occurrence, amplitude, and polarity across days, weeks, months, or years and statistically verify the expected amounts of lightning activity in your service territory.
An Exposure Analysis offers point-by-point and/or gridded analysis resolving the amount and type of lightning activity within user-defined asset buffer regions. It plots time trends of lightning over your service territory and/or assets, ranks assets by the amount and intensity of lightning exposure and discriminates by polarity and amplitude around user-defined asset buffers (e.g. 1 km around a power line).
