摘要: This paper highlights the earth fault problem in unearthed (isolated) and compensated neutral medium voltage distribution networks transient-based protection as a solution. The technique of analysis will be discussed considering sampling window, frequency data updating. required transient simulation its validation presented. Many important practical investigations also such measured quantities, polarity criterion, magnitude criterion suitable earth-fault indication tools. Finally, some developed techniques algorithms from previous work this area summarized.
