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 / bilal din

94 is ANSI code for tripping relay and 86 is ANSI code of
Louck out relay.
Both have specific fuction and can not be interchangable,
means we can not use lockout relay for trip fucntion and
vice versa,...
