Electricity Usage and Measurement
Electrical Diversity Factor Calculator
This page handles the arithmetic for diversity factor while leaving room to review units, limits, and source conditions.
Check Diversity factor
Electrical Diversity Factor updates live after each input change.
The Electrical Diversity Factor equation
Only the entries shown on Electrical Diversity Factor feed diversity factor. If another correction factor matters, keep it in the notes or make a separate run.
The formula uses Sum of individual peaks, and System coincident peak to produce Diversity factor. Unit mistakes usually show up as an answer that is off by a factor of 10, 100, or 1,000.
The Diversity factor value and any supporting metrics belong to this same Electrical Diversity Factor case, not to a nearby run with different inputs.
Sample Electrical Diversity Factor run
Using the sample values, Sum of individual peaks = 250 kW; System coincident peak = 180 kW, the primary result is 1.39.
This Electrical Diversity Factor one-input test is a scale check, showing direction and sensitivity without turning the changed case into a recommendation.
If the changed sum of individual peaks comes from a real measurement, keep the original Electrical Diversity Factor run so the source of the difference remains clear.
Source notes for Electrical Diversity Factor
Treat the Electrical Diversity Factor input panel like a short measurement log. If sum of individual peaks is assumed rather than measured, label it before copying diversity factor.
| Entry | Example | Check before use |
|---|---|---|
| Sum of individual peaks | 250 kW | Enter sum of individual peaks in kW. |
| System coincident peak | 180 kW | Enter system coincident peak in kW. |
What not to assume from Electrical Diversity Factor
Document the observation periods.
- Demand ratchets
- Taxes and fees
- Tiered rates
When diversity factor is close to a rating, use the stricter review path instead of relying on the extra decimals shown by Electrical Diversity Factor.
Electrical Coincidence Factor is a separate worksheet; carry over diversity factor only with its units and source note.
Reading diversity factor
The result card gives a comparison point for Electrical Diversity Factor. Equipment ratings, safety margins, and manufacturer limits still need their own check.
Electrical Diversity Factor is only useful when demand interval, tariff period, and metering basis match.
Audit trail for diversity factor
Store the meter period, rate schedule, demand interval, and whether the Electrical Diversity Factor value is before or after taxes.
If a later Electrical Diversity Factor run changes only sum of individual peaks, label it as sensitivity work. Several changed conditions deserve a new baseline.
Help with diversity factor
When should this be run again?
Run a new Electrical Diversity Factor case when the source condition changes, such as voltage, load, rate schedule, temperature, component, connection, or period.
What does a Check inputs message usually mean?
On Electrical Diversity Factor, Check inputs usually means a required entry is missing, outside its allowed range, or creating an undefined operation.
Can the default values be used as a recommendation?
No. The Electrical Diversity Factor defaults only demonstrate the form. Replace them with measured or rated values for the actual electricity usage and measurement case.
Why did the answer move so much after one input changed?
Many electrical relationships are proportional, inverse, squared, or tied to a denominator. A small change in system coincident peak can have a visible effect when the other entries stay fixed.
