MONITORING MODES
Monitoring modes
PX5 allows users to monitor events in the following setup categories: Standard Power
Quality, Current Inrush, Fault Recorder, Long-term Timed Recording, Continuous Data
Logging, and EN50160 Power Quality mode. Selecting any setup category automatically
sets trigger and capture conditions. Advanced users re free to mix and match settings
(see Chapter 6 Advanced Setup Options).
Standard Power Quality, Demand, Energy: PX5 algorithms automatically evaluate
existing rms and waveform conditions to optimize setups to reliably capture data. This
feature ensures that the first-time user gets the expected results, while providing the
experienced user with the ability to tweak settings for specific applications. Either way,
the necessary data used to identify critical events and optimize mitigation solutions is
recorded into the data card as it occurs.
Current Inrush: Determining system characteristics during current inrush conditions such
as impedance changes during motor energization or the I2t curve of a breaker trip is key
to preventative maintenance and enhanced power system performance. Inrush type
events such as motor start-up typically requires extended duration cycle-by-cycle
recording. With PX5, users can capture and store detailed data to evaluate system
performance against specifications and previous benchmark data. Under the current
inrush mode, triggers are current-based. By operating in the inrush mode, the instrument
will capture and store highly detailed data to a Compact Flash data card in real time,
then rearm and be ready to capture data during the next test run.
