  1. A new calculation method for sections has been implemented and is available for use on AC Mitigation Steady State (TT-11517, TT-11562, TT-11666, TT-11672). 

    1. Users will be able to choose between this method and the current method in calculations done for their case. 

    2. The current method for section calculations will be phased out permanently on 04/01/2025. 

    3. Negative distance, angles and local earth impedance approximation has additionally been updated. 

    4. Average section distance is now being calculated for the distance between the reference line and the surrounding lines 

    5. A detailed release note is linked to the application and available for review here: https://pipelineengineeringsoftware.com/Content/Downloads/Sectioning.pdf
