The powerful data acquisition and computing platform of the D90
resolution recording of power system parameters replacing the need for an expensive
stand-alone digital fault recorder (DFR), resulting in capital costs savings for the end user.
The digital fault recorder features a high-resolution transient recorder (fast scan), a long-
term disturbance recorder (slow scan), and a longer sequence of events with up to 8000
events. The internal clock used for time-tagging events can be synchronized with an IRIG-B
signal or via the SNTP protocol over the Ethernet port. This precise time stamping allows
the sequence of events to be determined throughout the system.

The D90 contains an advanced sequence of events recorder with the capability to
record up to 8000 events.
Sequence of events information can be accessed either through the front panel interface
or through the EnerVista Launchpad software. The very high sampling rate and large
amount of storage capacity available for data recording in theD90
need for installing costly standalone sequence of events recording equipment.
Plus
The D90 supports a fault report and associated fault location data. The fault report
stores data pertinent to an event that is triggered and provides the distance to the fault
location. A maximum of 15 records are stored in the nonvolatile memory providing a
comprehensive summary of events associated with a fault.
