Protection  Characteristics

3.1 Phase  Open  Function

    This  relay  contains  the  Definite  Time  characteristic  to  be  used  for  Phase  Open 

protection. 

It  operated  to  1  or  2phase  voltage  less  than  80%  rated  voltage  or,  angle  chaged  over 

range  based  on  rated  voltage.

Logic  Diagram  for  Phase  Open  element  operation  is  as  follows.
