What is 100%
protection of
generator? Why
95% protection
is used not 100%?
Answer Posted / sandip upare
Generator having lot of protections rotar-stator wdg. earth
fault,over voltage,over current etc.
For that each relay having setting from 0-100 per. with
time period in seconds
According to type of fault we have to set the setting
example :- for earth fault protection we have set upto 50-
70per. because if we set to 100% every and each small
leakage relay trip
so my thinking is only that the setting of each protection
is depend up application of DG only on what load
