Energy monitoring and submetering: a project selection guide
Useful energy monitoring starts with the question you need to answer: total consumption, tenant allocation, equipment demand, peak load or power quality.
Define the measurement
Record single or three phase, supply voltage, maximum current, circuits to monitor, mounting space and whether direct connection or CT measurement is needed. Identify the reporting period and required electrical measurements.
Match the meter and CTs
Check CT ratio, secondary type, aperture, accuracy and compatibility with the selected meter. Incorrect CT settings, orientation or phase association can produce misleading readings. Confirm wiring and commissioning requirements with your electrical contractor.
Connect the reporting system
Choose local display, pulse, RS485 Modbus, Ethernet or cellular communications as supported by the exact model. Allow for gateways, power supplies, antennas, data service and software configuration.
Scope the installation
Send a switchboard photo, circuit count, phase arrangement, current ratings, CT dimensions and communications requirements. Billing or regulatory use requires separate confirmation of the exact meter's suitability; monitoring capability alone does not establish it.
