Sampling
at up to 512 Samples per Cycle
The
unit can sample at up to 512 samples per cycle.
This allows a user to record high-speed transients
and anomalies on the line. The user selects
the sampling rate and channels to be recorded
on the line. Moreover, the Nexus can record
as many cycles as desired for the application.
There is no back-end limitation on cycles recorded.
Voltage
Surge and Sag Recording
Using
the unit’s RMS trigger, the Nexus will record
all Voltage surges and sags on the line allowing
a user to build a detailed power quality database
of readings and excursions. Using this information,
the user will be able to view waveforms and
plot CBEMA information depicting the amount
of damage the PQ events caused.
Fault Recording and Analysis
The
unit’s RMS trigger can also be used to trigger
for current fault on a line. The trigger allows
a user to view a graphic waveform of a fault
event. Using the unit’s high-speed status inputs,
the user can time relays and circuit breakers
allowing the unit to be used for system apparatus
monitoring as well as power metering.
GPS
Clock Sync.
The
Nexus monitor offers a built-in GPS clock sync
input allowing the unit fault and PQ records
to be timed to one millisecond. This is very
useful for conducting fault analysis using
the fault recording capability with the IRIG-B
GPS clock input, the user can use a Nexus as
a fault recorder timing multiple events through
a power distribution system. This capability
is available at a fraction of the cost of traditional
fault recorders with less capability. |
