Abstract: The invention concerns magnetic sensors and, particularly, a magnetic sensor arrangement for use in an electrical measuring device. In the device, magnetic sensors are provided within recesses formed in the arms of the device. The recesses are typically formed within laminations and act so as to shield the magnetic sensors from interference, whilst enabling them to detect a magnetic field of an electrical conductor placed between the two arms.

Abstract: An electrical measuring device has measuring elements for fitting around an electrical conductor, so that a property associated with the conductor can be measured. The device has a display unit 13 which can be used to display information relating to the property being monitored. The measuring elements for fitting the device around the conductor include a pair of jaws 16, 17, each mounted on a body member 12 for movement with respect to the body member, so that the jaws can move towards and away from one another. A plurality of connection terminals 25, 26, 27 and 28 are provided, together with a selection mechanism arranged such that, when at least one terminal is accessible, at least one other terminal is inaccessible. The device has an output terminal 29, from which an output signal can be derived, with isolation elements 35, 36 to isolate the output terminal from other components of the device, to avoid or reduce the risk that high voltages will be transmitted to the output terminal.
