Wizard Setup

Overview

Introduction

Wizard Setup guides the user through the circuit setup step-by-step, via a series of

screens prompting for information about the circuit to be monitored. The unit

automatically turns on the correct channels, sets the parameter thresholds and

waveform capture settings depending on the detected circuit type, nominal voltage and

current values, and monitoring mode specified by the user.

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 are 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 I

t 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.

Fault Recorder

: A fault in a wire circuit is usually due to unintentional grounding, a

break in the line, a crossing or shorting of the wires, etc. A digital fault recorder logs

extended duration cycle-by-cycle recording. Under the fault recorder mode, triggers are

voltage-based. PX5 can help locate failures detected in various components of assorted

equipment by recording an extended period of cycle-by-cycle data to capture the entire

duration of the fault and the associated system response.
