Patent ID: 8587399

Claim:
Split-core current transformer apparatus, comprising: a U-core section with two leg portions that are connected by a yoke portion such that the two leg portions are spaced apart from each other, said U-core section being nested in a base module with the ends of the leg portions are exposed outside of the base module; a closing-bar core section housed in a cover module that is connected pivotally to the base module in a manner that places the closing-bar core section in contact with both of the leg portion ends of the U-core section when the cover module is pivoted to a closed position in relation to the base module and that separates the closing-bar core section from the leg portions of the U-core section when the cover module is pivoted to an open position in relation to the base module; a secondary winding around at least a portion of the U-core section; and a latch mechanism that latches the cover module to the base module in the closed position, said latch mechanism including latch components in the cover module that are releasable from mating latch mechanism components in the base module by squeezing forces directed inwardly on opposite sides of the cover module, wherein none of the latch components in either the cover module or the base module protrude substantially outward from adjacent exterior surfaces of the cover module and base module in either latched or unlatched mode.
