Timely Detection and Emergency Management of Transformer Main Tank Issues

Often just viewed as a form of ‘insurance’, an appropriate on-line monitor can not only provide a timely detection of main tank issues but also provide, arguably, an even more significant contribution in the subsequent management of the event with the transformer remaining energised throughout.

Stepped Event Analysis

Stepped event analysis is one of the important additions in the upcoming V11 release of OneLiner™. A stepped event simulation begins an initiating short circuit defined by the user. The stepped-event logic then simulates subsequent relay-tripping and line-reclosing events until no further events are forthcoming.
