| Abstract |
Microprocessor distance measuring units with
adaptive tripping characteristic upper boundary to load
conditions are developed in this article. The analysis of the
impedance measured during the phase-to-ground faults is
carried out and mathematical functions for upper line of
tripping characteristic are obtained. The experimental
comparison of adaptive and static characteristics on the basis of
numerical experiment was carried out (Monte-Carlo method).
The results show that functioning effectiveness of distance
measuring units with the adaptive characteristics is higher than
with static ones. |
