what is the difference between the 94 lockout relay and 86
lock out relay. I have noticed that the 94 lockout relay is
activated when the distance realy is activated and 86 is
activated when the 87T differential is activated. but why
can't the same lockouts be used for both the protection
schemes
Answer Posted / ajay khandait.
Lockout relay is handreset relay in this case both the
relays are hand reset relay. only difference is that 94
lockout relay is used for line protection and can also be
provided with auto reclosing facility.
If the auto reclosing is not successful then in that case
94 goes to Lockout state and shall be manually resetted.
In case of 86 there is no Auto reclosing feature available.
It goes to lockout state directly.
