Power-quality measurement record
Measurement-record fields for voltage unbalance, harmonic THD and related Australian power-quality worksheets.
Power-quality readings to capture on site
List measurement-record fields without diagnosing the site condition or setting universal power-quality limits.
| Field | Purpose | Source | Boundary |
|---|---|---|---|
| Measurement set reference | Identifies the captured voltage or harmonic record. | Analyser record or site log | Do not mix readings from different times or loading conditions. |
| Instrument and setup | Keeps method context with the result. | Instrument record | Instrument configuration can change interpretation. |
| Load or operating condition | Shows what was happening during measurement. | Site observation or log | A measurement without condition can be misleading. |
| Entered review threshold | Makes calculator comparison transparent. | Reviewer, project, DNSP or equipment context | This table does not set universal limits. |
| Follow-up owner | Routes the result to the right project review. | Project record | Calculator output is not a diagnosis by itself. |
- Use this table to keep measurement context beside the result.
- Formal diagnosis needs analyser setup, site conditions, DNSP context and competent review.
Before measurement records are interpreted
Capture the measurement point, duration and instrument context before interpreting harmonic, voltage or unbalance results.
| Item | Value |
|---|---|
| Purpose | List measurement-record fields without diagnosing the site condition or setting universal power-quality limits. |
| How to use the source | Field table only; measurement formulas live on chart and calculator pages. |
| Standards and project context | Australian low-voltage power-quality context; DNSP, equipment, analyser setup and project requirements govern formal interpretation. |
| Where judgement is still needed | Use this table for lookup, labelling or worksheet context; do not treat it as a project-specific calculation result. |
| Before relying on it | Confirm current standards, local authority requirements, DNSP conditions, project documents and manufacturer data before relying on a decision. |
Standards basis for power-quality records
Review the standards context, checked date and Australian measurement scope before relying on a recorded value.
