Energy submetering
Create a metering hierarchy that explains where energy is used and who owns the data.
Decisions before procurement
| Decision | What to establish | Evidence to bring |
|---|---|---|
| Metering boundary | Separate incoming supply, tenant feeders, common services and process loads. Match each location to the reporting question. | Single-line diagram and feeder ownership |
| Measurement chain | Check direct versus CT connection, ratio, secondary current, accuracy and lead burden. | Current range, aperture and meter input |
| Data and commissioning | Agree protocol, reading intervals, retention and naming. Verify polarity, phase order and scaling against a known load. | Network access and commissioning record |
Your project brief
- Feeder schedule and current range
- Existing CT ratio, class and secondary rating
- Process/tenant/shared-services reporting purpose
- Protocol, data ownership and commissioning scope
Confirm the actual supply and control voltage. Kenyan projects commonly specify 230/240 V single-phase or 400/415 V three-phase; the selected equipment must match the measured supply and manufacturer rating.
