Abstract
The present disclosure is a system and method for measuring both load current and residual current within an electronic component. The electronic component includes a first toroidal core for measuring load current and a second toroidal core for measuring residual current, all enclosed within a housing. The system facilitates the measurement of load current and residual current in a small form factor and may be configured to replace legacy electronic components that measure only load current.
Claims20
A system comprising:
- a housing defining:
- a first port configured to accept a first conductor;
- and
- a second port configured to accept a second conductor;
- a first toroidal core disposed within the housing and configured to encircle the first port and the first conductor, the first toroidal core configured to facilitate measurement of a load current;
- and
- a second toroidal core disposed within the housing and adjacent to the first toroidal core configured to encircle the first port and the second port and thereby further encircle the first conductor and the second conductor, the second toroidal core configured to facilitate measurement of a residual current of a voltage direct current (VDC) circuit, the housing at least partially enclosing the first toroidal core and the second toroidal core.

A system comprising:
- a housing comprising:
- a first hollow cylinder which is a border of a first port configured to accept a first conductor;
- and
- a second hollow cylinder which is a border of a second port configured to accept a second conductor;
- a first toroidal core disposed within the housing and configured to encircle the first conductor, the first toroidal core configured to facilitate measurement of a load current;
- a second toroidal core disposed within the housing and adjacent to the first toroidal core configured to encircle the first conductor and the second conductor, the second toroidal core configured to facilitate measurement of a residual current of a voltage direct current (VDC) circuit, the housing at least partially enclosing the first toroidal core and the second toroidal core;
- and
- at least two pins configured to connect to two leads of at least one of the first toroidal core or the second toroidal core, the at least two pins further configured to electrically and mechanically couple the system to a wiring board.
