Technical reference manual
the fault sample and uses samples during 1/2 - 2 cycles depending on the shape of the
signals.
If no starting point is found in the recording, the disturbance report trig sample is used
as the start sample for the Fourier estimation. The estimation uses samples during one
cycle before the trig sample. In this case the calculated values are used both as pre-fault
and fault values.
The name of the analog signal that appears in the Trip value recorder function is the user-
defined name assigned when the IED is configured. The same name is used in the
Disturbance recorder function (DR).
The trip value record is stored as a part of the disturbance report information (ER, DR,
IND, TVR and fault locator) and managed in PCM600 or via the local HMI.
Function block
The Trip value recorder has no function block of it's own. It is included in the
DRPRDRE block and uses information from the BxRBDR block.
Input signals
The trip value recorder function uses analog input signals connected to A1RADR to
A3RADR (not A4RADR).

Introduction
The Disturbance recorder function supplies fast, complete and reliable information
about disturbances in the power system. It facilitates understanding system behavior
and related primary and secondary equipment during and after a disturbance. Recorded
information is used for different purposes in the short perspective (for example
corrective actions) and long perspective (for example functional analysis).
