In the resilient and reliable electrical power system, condition of high voltage insulation plays a crucial role. field integrity, partial discharge (PD) inception development trends are essential for assessment criteria in diagnostics systems. The observed trend to employ more sophisticated algorithms with machine learning features artificial intelligence (AI) elements is everywhere. classific...

Robust detection of monotonic trend of a data sequence, when the data is subject to gross errors, is investigated. The method involves detection of the outliers by using the statistics of the available data and eliminating or estimating them for better line fitting where the slope of the fitted line indicates the trend of the sequence. Examples demonstrate the performance of the method via Mont...
