Disturbance recording is initiated when overcurrent elements operate, a tripping signal is output,
2F or 5F element operates or external event signals are input. Three-phase overcurrent elements
1OCP-S to 3OCP-S are applied to the line CTs and neutral overcurrent elements 1OCP-G to
3OCP-G to the neutral CTs.
The initiations are blocked by the scheme switches.
Settings
The elements necessary for starting disturbance recording and their setting ranges are shown in
