Dynamic monitoring charts

Free-form charting of the electrical variables at any measurement point, at whatever granularity and window the analysis calls for.

A chart for each question

Where the dashboard gives a fixed view, Dynamic Monitoring Charts lets you build the chart: pick the variable, the measurement point, the resolution and the time window, and the platform draws it from the actual measurements.

This is the module you reach for once you know what you are looking for: correlating an event with a machine start, comparing behaviour across phases, or checking whether a pattern repeats by shift.

For long windows use 30 or 60 minute aggregation; for events and peaks, 1 or 5 minutes.

Available variables

Current per phase
Voltage per phase and per line
Active, apparent and reactive power
Power factor per phase and three-phase
Total harmonic distortion of current (THD)
Total demand distortion (TDD)
Demand
Voltage unbalance

How the analysis is set up

Four controls define the query, and the chart is drawn once data loading is switched on.

Controls

Load center and substation: down to the individual measurement point.
Granularity: one-minute, 5, 10, 30 or 60 minutes.
Hours to analyse: the width of the window.
Variable: the electrical quantity to plot.

What it helps resolve

Correlate a demand peak with the operation that caused it.
See whether a phase asymmetry is permanent or appears at certain hours.
Back the sizing of a capacitor bank or filter with the real curve.
Check the effect of a corrective measure by comparing before and after.

The variables it plots

Same point, same window, one selector — each variable answers a different question.

Current per phase at one-minute resolution — Current per phase at one-minute resolution: the ripple of each start-up stays visible.

Voltage per phase and line to line — Voltage per phase and line to line on the same chart.

Hourly average and maximum active power — Hourly average and maximum active power, plus active, apparent and reactive.

Power factor per phase and three-phase — Power factor per phase and three-phase: each vertical drop is an event that costs money.

Total harmonic distortion of current per phase — Current THD per phase: the step at 01:38 marks a change of regime in the plant.

Demand with the period maximum and average — Demand with the period's maximum and average lines.

Voltage unbalance across the day — Voltage unbalance: the jump at 13:00 gives away a load that came on unbalanced.
