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
