How To: Monitor Single Phase 2/3-core Cables
Most people would answer no; the current running through the live and neutral wires within the cable would effectively cancel each other out – the cancellation effect.
If you are using traditional non-invasive clamp meters they’d be right. The readings you get will be zero (or very close to zero).
For those sensors to work accurately you’d need to modify/cut/isolate the live wire to clamp around.
These sensors are the PowerZook and the intelliAmp:
POWERZOOK – PoE, SNMP, IoT
PowerZook is a standalone sensor which provides energy usage data to your SNMP-compatible NMS via the network. It is powered via any PoE switch and after a brief calibration process will provide power usage information to your NMS.
INTELLIAMP – iMeter Compatible Power Sensor
intelliAmp works in conjunction with our iMeter monitoring device to provide power usage information. The iMeter is also compatible with environmental monitoring sensors allowing users to combine power usage and environmental data for analysis purposes.
