A split core current clamp connected to the WiTTRA Current Meter measures up to 400 Amps AC current on the primary centre conductor. The clamp can be fitted around existing electrical wiring, rapidly reducing the installation time. By harvesting energy from the current clamp, the Current Meter can run without any external power source. The Current Meter connects to a WiTTRA Sense 360 which posts measurement data to the cloud.
