Can I certify the sensors for sub-metering accuracy? Can I use them for sub-metering applications?
The current sensors do not provide sub metering accuracy because they only measure current (and not voltage or power factor).
In environments where power factor and voltage are stable, the overall accuracy of energy (kWh) measurements over time is expected to vary between 2% - 8%. Many of our customers choose to use our current sensors in such cases, due to the ease of installation and low-cost vs standard sub metering.
