Clamp-on Current Sensors are devices allow the measurement of currents without having to
break the circuit, namely non-invasive. The most common application is for the
measurement of mains currents, but the available technologies allow the sensor to be
optimised for most applications. In essence, these are current transformer where the core has been cut, then clamped closed after installation.
The difference between a Clamp-on Current Sensors and a split core device is that a Clamp-on is designed to be installed & removed multiple times while the split-core is intended to be installed just once. There are also significantly different safety requirements between the two.
