próba zwarcia w strefie (chronionej)/poza strefą


Explanation:
Tutaj o zwarciu wewnętrznym/zewnętrznym, tj. w strefie (chronionej)/poza strefą (chronioną) w przypadku zabezpieczeń różnicowych/nadprądowych.
Np.: "W przypadku zwarcia poza strefą chronioną (punkt F1) prąd Ist jest znacznie większy od Id, co oznacza niedziałanie zabezpieczenia.
W przypadku zwarcia w strefie (punkt F2) prąd Ist jest znacznie mniejszy od Id, co oznacza działanie zabezpieczenia."
W powyższym cytacie (str. 40) chodzi o zabezpieczenie różnicowe.
