摘要：A detachable current and voltage sensor provides an isolated and convenient
device to measure current passing through a conductor such as an AC branch circuit wire,as well as providing an indication of an electrostatic potential on the wire, which can beused to indicate the phase of the voltage on the wire, and optionally a magnitude of thevoltage. The device includes a housing that contains the current and voltage sensors,which may be a ferrite cylinder with a hall effect sensor disposed in a gap along thecircumference to measure current, or alternative a winding provided through the cylinderalong its axis and a capacitive plate or wire disposed adjacent to, or within, the ferritecylinder to provide the indication of the voltage.
