CCM: Non-invasive monitoring of a multi-core power cable
up to 32 Amps
Typical current transformers require access to a single live wire. This is not practical where you have the live, neutral and earth wires in a single sheath.
The Contactless Current Meter (CCM) does not need any splitting of cables, needs no electrician to install and is completely non invasive. AKCP's non-invasive contact-less current meter allows you to monitor current (and power if you have a reference voltage) in 2 core or 3 core cables.
AKCP's unique current measurement technology makes measuring individual IT rack current and power simpler, and lower cost than ever before.
With an accuracy of +/-5% (on factory calibrated cable) and +/- 10% on in field calibrated cables, the CCM gives sufficient accuracy to check for sufficient power overhead in your data center for capacity planning. It can also warn when approaching the tripping point of your breakers, and be utilized for PuE calculations.
CCM is used in applications where you want to know if you're close to your circuit breakers limit, or if the appliance or circuit has any load or not.
Users may combine the non-invasive current meter with cabinet thermal map sensors. Using AKCPro Server can also combine current load, thermal map and differential air pressure and analysis.
CCM - based on electromagnetism - is able to measure the current against the current oscillation. It is about +/-5% accurate at best up to 10% accuracy, therefore it should not be used for billing applications, or where you need highly accurate monitoring. However, it is suitable for getting an alert if you are close to tripping your breaker, or if your circuit is active or not (a circuit can have voltage, but no current, meaning there is a live voltage source, but there is no load, i.e. the appliance connected to the circuit is off (for example: in your house, a light switch is off doesn't mean the wire doesn't carry any voltage. There is always voltage coming into your house, but if everything is turned off your current load would be 0 Amps).
