Abstract
This paper investigates travelling wave based protection schemes developed for high voltage transmission systems and their adaptation to medium voltage distribution networks in order to enable ultra high speed relaying (within a quarter of a cycle of the power frequency) on a medium voltage level. This further demonstrates that the travelling wave based protection provides a high speed and very accurate fault detection. The given method compares the polarities of current and voltage travelling waves measured immediately after the fault inception to determine the fault direction.
