Abstract
A circuit interrupting device includes a grounded neutral transformer core, a high frequency transformer core, and a differential transformer core nested within the grounded neutral transformer core and/or the high frequency transformer core. The grounded neutral transformer core and the high frequency transformer core are disposed in a stacked configuration with one another.
Claims22
A circuit interrupting device comprising:
- a current sensor core;
- a core assembly defining a longitudinal axis and including:
- a grounded neutral transformer core;
- a high frequency transformer core, the grounded neutral transformer core and the high frequency transformer core are stacked along the longitudinal axis;
- and
- a differential transformer core disposed within a cavity defined by both the grounded neutral transformer core and the high frequency transformer core.
3 more elements
A method of manufacturing a circuit interrupting device, comprising:
- arranging a plurality of cores into a core assembly, the plurality of cores including a grounded neutral transformer core, a high frequency transformer core, and a differential transformer core, each of the plurality of cores configured to selectively output a signal, wherein the step of arranging further includes:
- stacking the grounded neutral transformer core and the high frequency transformer core along a longitudinal axis defined by the core assembly;
- and
- disposing the differential transformer core at least partially within a cavity defined by both the grounded neutral transformer core and the high frequency transformer core.
